#HeiseiRetro #HelloKitty #Sanrio This item uses Velcro and can be adjusted for sizes 15-18cm. Please refrain from purchasing if you are looking for an item in new condition, as it has been stored for a long time. Although there are no noticeable stains, please forgive any oversights as it is a personal inspection. It will be delivered with simple packaging and anonymous shipping. I am sorry, but I cannot accept price negotiations, so please understand.
