Thank you for viewing this item from among the many listings. This is a set of 12 crayons that can be wiped off with water ☺︎ My daughter bought this when she went to Omocha Kingdom (Toy Kingdom) and kept it carefully stored at home. It's water-based, so it can be wiped off with water, making it clean and safe ☺︎ It's a limited edition item from Omocha Kingdom, so it's rare ☺︎ I hope someone will use it ♪ - Number of colors: 12 colors - Features: Crayons that can be wiped off with water Thank you for looking.
