SANRIO Sanrio "76,12 Down Hat Fabric: 100% Polyester Filling: Down 50% Feather 50% Lining: Cotton Reversible? Maybe. Used indoors 1 or 2 times during the cold season. Bought quite a while ago, and there's a small button on the inside, but the accessory (I think it was a hat string) is missing. For those who love Hello Kitty, how about it? Used item. Thank you.
