★This is Minnie Mouse's stamp holder★ Color: Pink New and unused. It has a built-in ink pad on the lid, so I believe it's a push-type stamp holder where you insert your stamp and push. The outer diameter is approximately 1.3cm, and the inner diameter is approximately 0.6cm. Since the details about which stamps can be used are unknown, it would be best for those who have used a similar product before to purchase this. Please understand that we cannot accept inquiries about size mismatches after purchase, so we ask for your consideration if you agree. Immediate purchase is welcome.
