This is a set of 6 dot crayons. I received them as a souvenir from a museum, and the manufacturer is unknown. They have been stored for a long time. Please understand that these have been stored at home by a private individual before purchasing. The blue crayon in the middle is broken as shown in the image. The other crayons have only been used once for testing and are mostly remaining. They will be packaged in a paper bag with waterproof protection.
