I previously purchased these from Envelope-ya.com, an online shop, for around 15 yen each. They were originally stored in the included plastic bags and kept in a closet. I'm not planning to use them anymore, so I'm offering them for sale. They're the perfect size for sending shop direct mail, invitations, or even for money envelopes, etc. These are unopened, but the edge of the plastic bag is slightly peeled. ⚠️ These were stored in a beauty salon. There is a possibility that small hairs may be mixed in. Please refrain from purchasing if you are sensitive to this.
