This is a 50-color set of Cray-Pas crayons from Sakura Cray-Pas. I purchased these about 10 years ago for educational purposes. As you can see in the photos, they have been used quite a bit. The back is also dirty, and my name is written on it since they were for educational use. I will erase the name with a marker before sending them. Please understand that these are used items before purchasing.
