Japanese-made health slippers, women's L size I bought these last year when I was going abroad, carefully selecting them for use on the plane to prevent swelling. They are made in Japan and washable. However, perhaps because the soles of my feet are too sensitive, the bumps on these were so painful (><) that I gave up on using them. They haven't been used much, but they are still used items, so please refrain from purchasing if you are concerned about minor details m(_ _)m
