Thank you for viewing. *Please read to the end to prevent any trouble. BMC Activated Carbon Fit Mask Regular size (approx. 95 x 175mm) 30 masks per box, PM2.5対応 (PM2.5 compatible) Disposable non-woven mask. Brand new, unused. I received this as a gift, but I don't have a chance to use it, so I'm selling it. Please check the condition of the box in the photos. Please understand that this item is stored at home and managed by an amateur before purchasing. ⚠️This product will be opened, the box will be folded, and the masks will be transferred to a separate clean bag for packaging. If you wish to have the item packaged in its original, unopened box, it will cost more for shipping. Therefore, it will be an additional 500 yen. Please let me know in the comments before purchasing. Please note that I cannot hold items. If you agree to the transfer, you can purchase immediately without prior comment. If you could let me know in a message after your purchase that "transfer is ok," it would be appreciated. Thank you. ⭐︎There are no smokers in my home. ⭐︎I do not have any pets.
