I love chalk makers they are the best. I love that you can use them on just about anything. They work great and they are nice and bright colors. These work out great for my son that is just learning his ABC ,123’s. We got him a board for his room and the marks work great on it. You get 8 different colors in the package. At first you will need to put the head of the mark and shack them until the chalk ink gets down and coming out. These Highlighter Fluorescent Liquid Chalk works great and easy to use for anyone of all ages. Packaged well. I was offered the opportunity to review this product for my honest and unbiased opinion.
