Tempera paint stick This is a popular set of 30 crayons, perfect for educational purposes. This product has been a hot topic on social media and even reached number one in the crayon rankings on Rakuten! I purchased this on Rakuten about two years ago and have been storing it at home. Since I received another set and have been using that one, I am selling this unused set. Non-toxic ingredients Fast-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
