But BEWARE the ink WILL disappear if you leave your papers in the hot car

LOVE the colors and high quality ink.

The only issue I have with them is that the ink is not the smoothest

ink is clear!

The ink erases completely and doesn't leave a bunch of eraser dust.

Also, don’t allow your ink to get hot (i.e. leaving in the sun) or it will disappear!

and I saw them as pure magic with how well they actually erased the ink

The erasable ink is fantastic and I pretty much refuse to use any other pen

Look at the image, you'll see how the ink doesn't flow well in the center leaving a channel with no ink

They have been great for filling out crosswords (the ink smears some but the newspaper quality is to blame there)

One of the pens that I've tried so far has insufficient ink.

I also do engineering homework in then since I can see the ink better than pencil and can still erase!

The ink runs out WAY to fast.

And the ink is actually pretty dark for a gel pen!

Yes you can erase the ink clean with the tip of the pen

Though the ink is heat sensitive and cannot be used on important forms or documents making it a downfall for me

Smooth writing, love how well the ink erases

It completely erases the ink

The only con is with any frixion pen is that they empty pretty quick and advise that you buy the replaceable inks (cheaper for more quantity) instead of rebuying pens every time (which can be more expensive)

It’s really nice to be able to erase the ink if I made a mistake.

Works great ink doesn’t last as long as traditional

I guess it was hot enough where I kept my book to erase the ink though I'm never outside with it for too long

Other than that, this ink is amazing

you buy a lot of replacement ink, you could eventually ware down the eraser on the back of the pen.-If you write on the same spot and erase it 3 or 4 times, it will eventually become difficult to write on that spot.-The clicker pens are better than the ones with the cap because if you like to put the cap on the end of the pen you will cover the eraser.-If you share your pen, some people might find it confusing to click the pen by sliding the click part instead of pushing at the end.-The ink erases from heat (140 degrees F) and can reappear from cold (14 degrees F)

Maybe it’s invisible ink now ;

The kids love to write "secret" messages to each other as the ink disappears with heat, but reappears if you put the paper in the freezer.

Perfect ink flow - love the colors and that these pens erase really well.

The ink doesn't smudge after it dries and erases cleanly

The ink is bright and vividly colored, and they write smoothly

Ink glides like gel and erases easily.

Once this happens, your ink is useless

They truly erase the entering ink off of paper without giving a smearing appearances

This is a great erasable ink pen that has a clean eraser that never seems to wear down

Just keep out of sun; Ink is heat sensitive!

Ink is fairly dark and the "frixion" erases the mistakes cleanly

I love them, they glide ink on paper very smoothly the first time used

The ink is a scientific wonder and erases with ease

The ink is smooth in texture

, how much I tried to 'suck' the ink out of the pen tip, or how much I used any of the regular methods to make a pen work again.

The ink gets erased WHILE writing:(Plus the ink flow isn’t smooth

The pens all were all" writing" with basically clear ink and useless when I went to use them .

The ink is very light/faint, but the eraser works well and leaves no marks behind.

The ink writes perfect and erase with no trace of ink left

They all looked like they had ink in

but when you erase the ink, it still somehow leaves a very faint trace on paper.

Nice smooth ink and very easy to erase

I left mine in my car for a few days and now the ink is clear.

This ink rolls on paper with ease, erases clean and great to doodle with or take notes in class

The colors are fun and the ink is easy to write with

Erasable ink is so fantastic to show kids different steps and allows me to correct mistakes without having to start over.

So I couldn't use the pens on anything official of things that needed to last a while because the ink wasn't reliable to still be there

These pens are great but the ink does run out pretty fast but that is basically all that is bad the ink is very vibrant and

Unfortunately, I have used a ton of eraseable pens in which the ink is just dull and blotchy

The ink is very light/faint, but the eraser works well and leaves no marks behind.

The ink writes perfect and erase with no trace of ink left

Another thing i dont like is the ink runs out very quickly.

I do wish the ink was darker, though

Entirely different from the gummy, sticky ink in the first generation of erasable pens that I used long ago

The ink erases perfectly with no smearing.

they contained enough ink to last me about 1 week before they were ALL empty and no longer working

It will turn the ink invisible

The ink itself is inconsistent

The ink is dark and legible.

Also, a tip for crafting, if you draw on clothing you can erase the ink at the end of your project by ironing.

I always loved the idea of erasable pens but the erasers always just smudged the ink

The ink is a scientific wonder and erases with ease

Smooth ink, great erasure, bright colors.

Great, not enough ink.

Eh, the ink runs out fairly quickly and sometimes smudges when you try and erase it

(You just do it firmly and fast so the heat removes the ink)- fantastic product!

The ink flows smoothly and erases completely.

Good ink flow, great clean erasing.

For some of them (e.g. red), the ink is not very dark.

Do not leave them in your car on a hot day or out in the sun because then you’ll completely destroy them and the ink will become invisible

Amazingly, the ink can be totally erased!

The ink will erase if left out in the hot sun or exposed to heat, not a common problem though.

The ink dries quickly and doesn't smudge

Bought on a recommendation, but these pens tend to smear, lose ink quickly, and fail to give a nice, dark, full line

I wish the ink was brighter

My black ink never worked so that was disappoint

It doesn't smudge the ink!

Importantly, they don't smear (though, like most rollerballs, the ink is water-soluble

They use friction to erase the ink

The only con is with any frixion pen is that they empty pretty quick and advise that you buy the replaceable inks (cheaper for more quantity) instead of rebuying pens every time (which can be more expensive)

Yes you can erase the ink clean with the tip of the pen

Great pens with smooth flowing ink that don't *usually* skip

The ink can be erase with heat

I love having multicolored inks which is the draw for me but come on, this is rediculous!!!!!!

The ink is bright and no skipping or smearing

In a short two months the ink is dry -- complete waste of money,

and I haven't had any problems with the ink skipping or leaking

These are the best ink pens ever

I came into the review agreement with very very low standards and the hope at least the pretty ink would be worth my time

The only thing I could benefit from is using the eraser to remove the ugly ink.

The erasable ink is fantastic and I pretty much refuse to use any other pen

and I saw them as pure magic with how well they actually erased the ink

I barely used them and then they acted like the ink dried up or ran out

but I think they have delivery issues getting ink on paper.

Great ink

Now that I know this pen erases ink BETTER than a pencil erases lead, its a winner.

Ink glides like gel and erases easily.

The only thing keeping it from 5 stars is I wish the ink was a little darker

They worked exactly as described, but after 6 months I noticed the ink wasn't as vibrant in the pens I used the most

Smooth-writing erasable ink in vibrant, intense colors - what could be better

They erase the ink without a trace and the rubber eraser end doesn't even go down

I tired to write with them and the ink was not working.

Easy to write with, and also easy to erase the ink

Must have something to do with the way that the erasing works, maybe the friction of the eraser rubbing on the paper disolves the ink

I like being able to erase the ink however it does fade after a few days.

I do not have the best handwriting and being able to erase ink is the best.

some ink isn't great.

The only downside is the ink disappears with heat

Sometimes it seems like the ink goes too fast but that is the only complaint.

The ink is fine when I run it through my scanner

The ink erases well.

They have always held up well, the ink glides on smoothly, no clogs.

The ability to erase ink is great

and I love that the ink is erasable, much tidier than the white correction tape.

Takes 10-15 seconds to dry, writes too thick, and runs out of ink too fast

The writing is smooth and effortless, the colors are good, and the ink becomes invisible (erases), using the friction eraser.

but I wish the ink was darker.

The ink is super smooth, and ACTUALLY erases

I love these pens but one pack, the ink was completely dried and did not work.

Keep ink away from heat, like your car

Well worth the price - but I took off one star simply because the ink smears with moisture -- not enough to be a real problem, not even as badly as most inkjets, but it does smear.

The ink writes well

The capped pen doesn't lay down ink as boldly, but these Clickers really do a nice job

the ink becomes invisible as stated.

Great quality ink and smooth

I love these pens but one pack, the ink was completely dried and did not work.

The ink is super smooth, and ACTUALLY erases

writing on will erase the ink

I use them frequently and the ink lasts well.

so it seems like the heat has dried the ink so it’s streaky , in my opinion it’s not worth 10 dollars

My favorite part is erasing the ink

The ink erases well.

See how faint the ink is in the above picture

Sometimes the ink in one of the pens goes light for a few words but other than that, love them!

The ink is very easily erased and the color is very bright and pigmented.

Ink is very smooth, and I am impressed by erasing abilities, but it's not perfect

Do you words look like chicken scratch like mine?These are the set of pens for you.. nothing like being able to erase mistakes =) ink flows smooth, and i get to correct my doodles

The ink has that common ballpoint pen problem where the lines aren’t totally opaque

These are pretty good ink considering they are erasable

Must have something to do with the way that the erasing works, maybe the friction of the eraser rubbing on the paper disolves the ink

Like the ink - goes on the page easy

Great color, smooth ink flow and a nice weight.

Vivid colors, both ink and pen

The ink erases completely.

The ink doesn't bleed through the pages and is easy to erase if plans change.

But beware, the ink can fade away at times so do not use these for any permanent use, especially on checks.
