Thank you for viewing! This is a set of 23 white envelopes. I purchased a pack of 25, used 2, and then stored the remaining envelopes in a drawer. I no longer have a use for them, so I'm offering them to someone who needs them. ● Size: Nagagata 4 (90 x 205mm) *B5 size paper fits when folded in quarters. ● With tape (one-touch type, no glue needed) ● Double-layered, so the contents are not see-through ● For standard mail *When shipping as an outer envelope on Mercari, this size cannot be sent via Nekopos. ■ There are some folds and stains due to aging. Also, the outer bag may be torn upon opening, and the tape may have lost some of its adhesive strength. I will put them in a new OPP bag when packaging. I have other items for sale as well. If you purchase multiple items, I will offer a discount for the difference in shipping costs. Please comment before purchasing, and I will change the listing. ★ Discounts cannot be applied after purchase due to the system. ★ Discounts on this item alone are not possible due to the system. For packaging, I will put them in a new OPP bag to protect them from water damage, use cardboard to prevent folding, and ship via Yu-Yu Mercari's Yu-Packet Post. *I may use recycled packaging materials. ■ Please refrain from purchasing if you are sensitive to items that have been stored at home for a long time. #MASHIRO's Other Items
