Thank you for viewing. This is a set of 6 boxes of Iris Ohyama pleated masks for elementary school children, each box containing 30 masks. I purchased these for my children, but they have outgrown them, so I am selling them. All items are 【new and unopened】. Shipping will be done with measures to prevent water damage, and will be sent via anonymous delivery. Please note that the shipping method may be changed from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin. Thank you.
