This is a discontinued San-X letter set. It says "1994," so it's likely from nearly 30 years ago. "Le chant du Ciel" SAN-X For standard mail Letter paper (2 colors) 12 sheets, Envelopes (2 colors) 6 sheets Letter paper size: 16 x 20 cm MADE IN JAPAN *The envelopes are made of thin paper, like tracing paper. It was stored for a long time in the warehouse of a shop run by my grandparents, so it is an unused item that has never been in anyone's hands. As this is a retro item, there are small stains, discoloration, and small tears in the plastic bag (see photos 2, 7-10, etc.). Please understand this before purchasing. m(_ _)m ☆I am also selling other discontinued San-X stationery. #cottonrose_sanx ☆Other letter sets 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. (^-^) *Since this item is also listed on other flea market apps, priority will be given to the buyer who purchases it first. Also, I may suddenly remove the listing due to this.
