Letter Set Post Office - Stationery, Envelopes, Organizer File - Retro, Showa Era - 2 Sets

Post Office Letter Set
Retro Showa Era
Set of 2, sold together

This is a prize won from a Post Office lottery from a long time ago.
Each side contains stationery and envelopes.
There are also 5 pockets.
You can put stamps, cards, stickers, etc. together and use them.

Each set includes:
- 7 Owl letter sheets
- 5 Owl envelopes
(Adhesive type, requires water to seal)
- 7 Bird vertical letter sheets
- 4 Bird vertical envelopes
(Peel-off adhesive strip type)
And there are 2 sets of these.

New and unused, but the case has some discoloration, wavy areas, and dirt due to age.
The stationery and envelopes are in good condition, but there might be some discoloration due to age as well (it's hard to say for sure as I don't know the original color).

This is a long-term home storage item.
Please understand that there may be minor oversights.

*The postal code format is the old 5-digit style.
Please be aware ??

Please refrain from purchasing if you are concerned about minor details.
Thank you for your consideration.
