The yellow and white did work very well on the glass surfaces.

The ones that work are great, but 3 of the colors have scratchy tips and they don't write smooth at all no matter how much I try to use them

These markers worked really well and look bright on our black chalk erase board

these chalk markers work really well and i like the bright colors

I put the calendar in a poster frame and these markers work well on the plastic.

Colors are very vibrant but hard to write small lettering.

Colors are vibrant, and the liquid chalk flows well after priming the pens for use.

The good: Colors are very bright and vibrant - The bad: chalk does not just wipe away with a chalk board eraser... you must use a wet cloth of chalk board cleaner

but it can be easily removed if you have a magic eraser

They do not fully erase, even after scrubbing with a magic eraser.

I had to scrub and scrub with the magic eraser in order to get most of the chalk off the board.

Even magic eraser isn't working

I have to use a magic eraser and scrub to get it to come off.

They write very well (solid lines), and they erase so easily

Amazingly, the lines are not broken, and look very well.

They write very well (solid lines), and they erase so easily

The tips catch on even smooth surfaces and don't provide a smooth, solid chalk line

I really like that the markers have two tips for either fine or thicker lines

All you have to do is shake the pen and press down a few times to prime the tip and then the chalk is smooth flowing.

These pens make it so much easier and the colors are bright and definitely readable.

I love these brightly colored chalk pens but don't use them on regular chalkboard or you will have to repaint it .

So far these are the best liquid chalk pens I have used

These pens are so easy to write with and the colors are so bright and vivid.

The chalk erases easily with water and the pen can be used to write fine or bold print.

So far these are the best liquid chalk pens I have used

It is unfortunate however that they can't be used over chalk paint.

Love these markers using on a sign and working great on wood going to seal it and then add wording just great colors.

These chal markers are the best chalk markers I have used

Could be that the mini chalk board isn't the right quality for this NOT to etch.

These seems cheap and aren't as good as other brands (especially the Chalk Ink, which is the only chalk markers I've found to be of good quality.)

But Versachalk is everything I wanted and the quality is outstanding!

High quality chalk markers that are easily shaken down and write nicely on chalkboards or any smooth surface

I usually use a different brand bought from an arts and craft store, the versachalk markers are more affordable and better quality

This is a great product, BUT it won’t work with the rain.

This product has ruined two of my brand new chalkboards and I am beyond disappointed that this product is still being sold on AMAZON

It still comes out, but with a lot of elbow grease or cleaning product

Not a product flaw, more so just a personal preference.

This product stained and ruined the chalkboards I purchased to reuse them on.

I used the markers last night and tried to "wet erase" the chalk and guess what, it would not erase.

I have since replaced my makeup with these Vibrant, colourful, liquid chalk markers and they are so so good

These awful "chalk markers" just ruined my $170 BRAND NEW chalkboard

So far these are the best liquid chalk pens I have used

Initially, we used white chalk but that didn't work out so well.

I tried that and they lack vibrance and stain the chalkboard

I have a dry erase board and a chalkboard in my kitchen that I love to write on and change often.

My daughter has a chalkboard in her room, and these chalk markers worked out so nicely

However it doesn't erase and I've ruined a great chalkboard now.

I will be sure to buy an authentic chalkboard and because I love good customer service!

I have used these a great deal on tempered glass I use as a dry erase board during classroom lessons

So far, I've used them on glass, plastic, a black board, skin, a dry erase board, and art paper.

I have been using them on a white dry erase board - obviously not the white one
