These are letter sets I've collected as a hobby. Some are the type of stationery that can be sent with a postcard stamp (folded in half and sealed to become a postcard). Most are sets of one envelope and two sheets of writing paper. In photo ②, the item at the top right has one envelope and four sheets of writing paper. In photo ③, there is one envelope and one sheet of writing paper. In photo ④, there are two envelopes only. In photos ⑥ and ⑦, there are seven postcard-type sets. There are a total of 40 sets (plus some, as the envelopes-only are not counted). The writing paper has all been folded and stored in envelopes, so there are creases. Some have old postal code boxes, so I will include "new postal code stickers." There may be some creases or slight discoloration due to the passage of time. Some are quite retro, but I would appreciate it if you would consider them if you understand. Thank you.
