This is a set of 10 Letter Pack Plus envelopes. The old-style envelopes (520 yen) have an 80-yen stamp affixed. They will be folded and shipped via Letter Pack Light, so please be aware of this. I will ship them out on the same day if possible, but it may not always be feasible. If you need them urgently, please confirm availability in the comments before purchasing. I can also sell different quantities. If you would like a number of envelopes other than what is listed, please let me know in the comments. These are items stored at home and are used. Please refrain from purchasing if you are sensitive to this.
