Ordered them thinking that it would work on the classic write on board. Could not get them to work. Not sure why unless the liquid has dried up. Will be asking for a refund

Very nice markers. I have worked with chalk markers in the past and love these ones! They are smooth and fluid to draw with.

Just what I needed, works great.

Loved those white liquid chalk markers! They are easy to use, no fuss, nothing to clean after. And the fact that you can use the thin or bigger pen is a plus for me. I recommend this set!

Awesome product for when you want that chalk look but with a controlled way of writing. Used it on a chalkboard label and it worked great.
