Combine this with a good paper like Rhodia, and you have a hassle-free way to get some of the best fountain pen performance I've ever experienced.

Love my Namiki pens.

The color is very good on this and it rolls off my fountain pen very well

He has recently decided to upgrade from the "best" pre-filled pen to a fountain pen that must be filled with cartridges

Looking for more affordable fountain pens that take these cartridges.

I managed to buy a nice fountain pen for my husband that absolutely NO STORES in my city carried refills for

Needed for my new great for my newly purchased Pilot Vanishing Point Collection Retractable Fountain Pen

I haven't used any more expensive fountain pens, but the Pilot Metro is very nice with this ink, especially for the price

I have to have my pen upside down just so it doesn't leak into the pen cap

My search for affordable fountain pen compatible paper continues

These cartridges, in an F-nib Prera, make an outstanding combination for a no-frills, non-skipping, fine-line pen.

These are working very well so far with the PILOT Vanishing Point retractable fountain pen

NOT DESTROY MY PEN.

I no longer have use for these, since the pen I bought is terrible.

I even cleaned my pen again thinking that the new ink was blending with my old ink... nope

I love Pilot pens

Followed the instruction, only to destroy my pen.

They are all attractive pens that stand out in the endless sea of disposable writing instruments

Love the pilot pens and this ink...smoothest writing ever and in doesn’t dry on pentip

Refills for Pilot fountain pen, easy to put in and, remarkably no ink stains any where

Not only did these not fit my pen (which was my fault since I missed that it said it was just for pilot pens) but this runny as all get out

Awesome writing pen

Great pen , great flow, good ink

My husband loves pens in general and a new pilot fountain pen I bought for him

I like blue black ink because its dark color isn't typical of cheap pens - it's interesting without being a novelty

yes. for the right pen.

Make sure to clean your pen before putting in a new colored cartridge or the ink will come out gray

I LOVE my fountain pen, and this ink does a great job

Well, it fits my pen, only so much as in the tube

I love all my Pilot pens

How awful that Target sells a pen and not the refills.

Very nice pen, great value!

I hope this didn't ruin my pen.

For the price this is an outstanding fountain pen

Though my Pilot ultra fine fountain pen came with one cartridge, it didn't come with English language printed instruction

Interestingly enough, the pilot varsity blue fountain pen with the medium nib is the exact blue I thought it would look like

I was given a very nice handmade fountain pen by one of my customers and I was looking forward to using it

they work perfectly in my perfect pen!

I purchased an amazing pen from Pilot, but I only recently discovered that I need to purchase cartiages that will fit this pen, no matter what color I wish to write with

I love fountain pens and even more the convenience of ink cartridges

This is a cool color that works in my all time favorite very best pen.

Great performance, cheap, yet another reason to like my Namiki pens.

I love my fountain pen

I buy these cartidges for the Pilot Namiki Vanishing Point Retractable pen which is amazing in itself

Love my fountain pen and it fits perfect inside of the pen

This should leave me enough ink until I decide to upgrade to a better fountain pen and just buy entire bottles of ink.

Great refills for an exceptional pen

Love the pen and love these cartridges, I remember struggling with fountain pens many years ago but thought I would try again

There is not much to say, the Namiki pen is a uniquely useful fountain pen and this is the only ink to consider for the pen.

If you push too hard you may either destroy your fountain pen, or have the cartridge leak through the bottom

I have had a similar experience with my all time favorite pen the uniballl vision elite

It's amazing that a pen as inexpensive as this could write so smoothly and effortlessly

The only problem with the cheaper varsity pen is the nib...medium is too thick

12 refills for what a fancy gel pen would cost, easily worth it

Pen is defective nice but defective it needs to be better next time but it is a very nice pen

I can finally enjoying this pen

It is extremely smooth and never clogs your pen, but dries out quickly

So a little over 5 bucks a year, not that bad, but I am sure they are making all there money on the ink, the pen is nice and cheap.

The retractable pen is my favorite of all fountain pens

The downside to it is it only fits Pilot/Namiki Pens that use cartridges, and as an example, I'm using them in my Pilot Metropolitan (which is an amazing pen for the price by the way!

product arrived on time, was well protected, came as advertised. if you like fountain pens, this product is for you

my husband loves his new pen!

Very good pen, particularly when you consider the low price.

My secretary bought me this great Pilot fountain pen, but with only two cartridges.

Plus they size didn’t fit pen well.

I love the pilot fountain pens and these work great.

Yep, fantastic ink for an awesome fountain pen, I won't disagree with that at all.

Fits in vanishing point fountain pen really well and does not leak

These load easy without the mess of a well pen

I love my fountain pen and this is a great refill cartridge but the purple is so dark it's almost black

After all of those modifications, I am happy to say that my pen is now flowing ink beautifully!Others have complained about these leaking

This nifty little refills fit the above-mentioned pens and work pretty well, they just push in and flow pretty fast

Great pen easy to refill

Great Pen.

Dries quickly enough on a fine nib pen to allow left handed writers to enjoy the experience of writing with a fountain pen

I love fine point pens and with the pilot ergonomic pen this works fabulous

The pen in which I use these is the only pen I don't use a converter because I like the way the pen writes with these cartridges

I recommend it it as well as the pens.

Works in the Pilot retractable pen perfectly.

Love pen

I love my fountain pen and these refill cartridges are the best I've found so far.

I am big on writing letters and carry my pen with me to work and pretty much anywhere I go

I love my Pilot Preara pens.

Pen is defective nice but defective it needs to be better next time but it is a very nice pen

Love the pen, love the refills...
