I'd like to inform you that the shop name was written on the back of the plates with a permanent marker, and I erased it with a sponge. Regarding the blue masking tape area: The shop name couldn't be completely removed and remains faintly visible. I would appreciate your understanding. If you'd like additional plates: I still have several in the warehouse. Let's discuss the additional price later. Regarding long-term storage: Please understand that there may be age-related deterioration. Thank you for your understanding.
