Yo-kai Watch Sleeper There is no size notation, but a slender child who is 120cm tall and usually wears 120-130cm clothing was able to wear it! I think slightly larger children can wear it too. The actual size is about 47cm in total length. There are black marker stains in places because it has been marked with a marker and washed. Please consider purchasing only if you understand that this is a used item and has been stored at home. Children's Sleeper Vest
