Minnie Mouse letter set. It's from around 1975. I treasured it so much that it's still unopened, so I haven't checked the contents. It's likely a set of writing paper and envelopes. It has been stored at home for a long time, so it appears to have some discoloration. "See image 5." There may be unexpected deterioration if opened, but I plan to hand it over unopened. Please consider this before purchasing. Immediate purchase is welcome. Please refer to images 3 and 4 for the size.
