Thank you for looking at my wonderful products! I think this was a souvenir from Taiwan, and it's been sitting in a drawer for a long time! I hope it finds a new home! Approximately 15 x 13 x 3cm I'm quite a clean freak, so I pay attention to hygiene, but it's been stored in a personal dresser. This is just my personal opinion, so please refrain from purchasing if you are overly concerned. Also, I apologize for the length, but please also read my profile! Thank you very much.
