These are cookie cutters in the style of characters from Demon Slayer. They're super cute! (*^o^*)ノ I bought them but never had a chance to use them, so I've been storing them. Would they be good for your children's play with clay, too? 〈Size〉 From the top of the head to the tips of the feet, Approximately 6cm to 7cm They will be shipped in a Yu-Packet Plus box. (^^)
