The Liquid Chalk Markers by Linkyo are as described on the description page. There are a total of ten chalk markers. Each one of these needs to be shaken well and primed by pushing down on the tip several times until the liquid chalk color appears then you are ready to be creative. I like that they can be use on all sorts of non porous materials like glass, mirrors, marker boards and chalk boards. These prime very easily and are fun for people of all ages. If you have a sports star in the family you can write on the windows of the cars celebrating the game. You are able to leave messages on mirrors for that special someone. These are great to use and wipe off with a water or sometimes with soap and water. Be sure to check on a small part of the material you plan to use it on first. I received these liquid chalk markers at a discount for my honest review.
