This is a stamp set with a Hello Kitty signature pen. It's unopened, but it's an old item, so deterioration over time is possible. The appearance looks to be in good condition, but I haven't checked the contents, so there may be defects such as ink leakage or the ink not working. This item is for those who don't mind minor details and for collectors. I think it's very rare as it's a stamp with Daniel-kun as well. Please consider this valuable item. Please check carefully and purchase only if you are satisfied. Thank you for your understanding.
