ONUPGOWhite Liquid Chalk Markers Pens 2 Pack, Chalk Markers for Chalkboard Signs, Windows, Blackboard, Glass - Kid Safe, Non-Toxic, Water-Based, Dustless & Erasable |3mm Reversible Bold & Chisel Nib

For the price, these are decent chalk pens. Thy are not perfect, but they do the job. They write smoothly and (once dried) hold up well. The only issues:-They leak very easily. Mine bled all over my hand on the first use and filled the cap with white ink.-They definitely need to dry for a minute before you can touch them, or they will smudge.

Only one of the pens worked. The other only writes weak on my labels. I’ve used this type before and I know how to prime them. I’m very disappointed. It wasn’t worth the gas to return them.

I love the pen that works. Not both pens worked. It’s why I gave three stars, Otherwise, I would have given the product five stars.

This chalk marker is pretty awesome. I bought it for a chalkboard calendar. It took a while to prime the tip. If you are not using them consistently it seems like you have to reprint the tip. Works better if you can write straight down vs. horizontal.

Works well for my artworks. I use them in alot of my Art on wood, canvas and glass.

Great product,easy to use

Writes beautifully, crisp clear chalk lines. Cleans off easily if cleaned within a day or two, however I'm not sure if it's my chalkboard or the marker, but some writing that I tried to erase a week later had stained and could not be erased and left some "ghost" writing, even with soap and water. Other than that I love this chalkboard marker. Excellent value.

The product worked well and was just what I needed for my chalkboard labels.
