(Yamanishi Co., Ltd.) Deodorizing Crepe Underwear These are the so-called long underwear that fathers and grandfathers wear. Since one piece was used, the contents are one piece. Please understand. They are knee-length and made of cotton, so they seem to be cool and comfortable to wear. It seems to be a product that is not often sold at a discount, so it's a good deal. When shipping, it will be compressed and recycled materials will be used. Thank you.
