This is a set of 20 Letter Pack Plus envelopes. 80-yen stamps are affixed to the old-style 520-yen envelopes. Please note that items will be sent in a bag and wrapped in bubble wrap for simple packaging. I will ship on the same day if possible, but it may be difficult. If you are in a hurry, please be sure to confirm with a comment before purchasing. I can also sell the desired number of envelopes, so if you want a different quantity than what is listed, please consult with me in the comments. Please refrain from purchasing if you are nervous about used items stored at home.
