This is a pair of unisex samue (work clothes). There is no quality label, but based on the manufacturer (REPOS)'s homepage, it appears to be vaniran fabric. It has a smooth, slightly rough texture, similar to linen. *Vaniran fabric is a dobby weave that resembles "tapa," traditionally used in Micronesia and Hawaii. Its characteristic uneven surface reduces skin contact, providing a cool and comfortable feel. It is often woven from cotton, but some are blended with other materials. This item is sold at Gyoza no Manshu Tomeikan, and features a print of Manshu's mascot, Ran-chan, on the back. Photos 9-12 are from the manufacturer's homepage (the actual product does not have elastic cuffs on the trousers). I received these as a souvenir, but I have no use for them, so I am selling them. The green one is unopened, and the maroon one is unused, but without the outer bag. ●Sizes: Green: L Maroon: M
