This is a discontinued San-X letter set. It says "2003," so it's likely from nearly 20 years ago. "Sakuradayori" (Cherry Blossom News) SAN-X For standard mail Letter paper (3 designs) 27 sheets, Envelopes (3 designs) 9 sheets Double-sided stickers Letter paper size: 14.0 x 18.3 cm MADE IN JAPAN It was stored for a long time in the warehouse of my grandparents' shop, so it's an unused item that has never been in anyone's hands ☆ As this is a retro item, there is a slight stain on the top sheet of letter paper (9th photo). Please understand this before purchasing m(_ _)m ☆ I am also selling other discontinued San-X stationery. #cottonrose_sanx ☆ Other letter sets can be found here ↓ #cottonrose_letter ************************************* ☆ I am also selling other Showa retro stationery and novelty stationery items. #cottonrose_retro If items can be bundled, I will offer a small discount, so please comment before purchasing (^-^) ※ As this is also listed on other flea market apps, priority will be given to the buyer who purchases first.
