Tempera paint stick This crayon set of 30 colors is a popular educational crayon. It's a product that became a hot topic on social media and even ranked number one in the crayon category on Rakuten! I purchased it on Rakuten about two years ago and have been storing it at home. I received another one and have been using that, so I am selling this unused item. Non-toxic ingredients Quick-drying Can be used on various materials such as paper, glass, and wood products. Please understand that this item has been stored at home. Shuttle Art
