This is a discontinued letter set from San-X. As it says "2000," it's believed to be from almost 25 years ago. "PALETTE" Simple*Works SAN-X (San-X) For standard mail 48 sheets of writing paper (4 designs), 24 envelopes Size of writing paper: 14.2 x 18.9 cm MADE IN JAPAN The envelopes are transparent, allowing you to see the design of the writing paper. It's a new, unused item that has never been handled by anyone, as it was stored long-term in the warehouse of a shop run by my grandparents. Due to its retro nature, there is some slight discoloration on the edge of the top writing paper (see photo 7), and the product label sticker is slightly torn (see photo 8). Please understand this before purchasing m(_ _)m ☆ I am also selling other discontinued San-X stationery. #cottonrose_sanx ☆ Other letter sets are here ↓ #cottonrose_letter ************************************* ☆ I am also selling other Showa retro stationery and novelty items. #cottonrose_retro If the items can be combined, I will offer a small discount, so please comment before purchasing (^-^) ※ Because I am also selling on other flea market apps, I will prioritize the buyer who purchases first. Also, I may suddenly remove the listing.
