Thank you for viewing. These crayons are made from rice and vegetables from Meguro, Tokyo. They are made with safe materials so that even small children can play with them without worry. In the unlikely event that a child puts them in their mouth, they are made with safe materials. I received these as a gift, but I will not be using them, so I am offering them for sale. I do not have any pets, and I do not smoke. 2,200 yen Japanese-made vegetable-themed crayon set, 10 colors. - Number of colors: 10 - Made in Japan - Design: Vegetable motif
