I believe this is something I used when I was a child. It hasn't been used much, so there aren't any major stains, but I think there is some aging. Approximately 348cm x approximately 15cm There is a camphor-like smell. Only those who understand that this is a used item, please. It will be placed in a waterproof plastic bag and shipped via Mercari delivery. It will be folded up, so please be aware of new fold wrinkles.
