Unicharm Super Comfortable Mask White Regular Size, 5 masks per pack x 20 packs (100 masks) Selling because they don't fit me. Purchased at a convenience store. New and unopened, but stored at home. Please understand. I have other items as well. If you want to buy in bulk, please comment before purchasing. I would appreciate it if you could select eco-friendly shipping to reduce shipping costs.
