This is a medium-sized Totoro ring purchased from Donguri Kyowakoku. I believe it's probably no longer sold. The acorns and yellow diamond charm are very cute. The size is unknown, but it fits a pinky or ring finger (it might be difficult for other fingers for adults). It has been used only once or twice, but it has been stored for a long time, so please purchase it if you understand that it is a used item.
