This is a product from Hip Co., Ltd. I believe I purchased it a few years ago at a drugstore (Kirindo). I think I wore it a few times when I bought it, but it's come out now. I had forgotten about its existence. There is a thin tear of about 4cm on the left side (although there is no hole), and there are white fuzz balls all over. I have uploaded close-up photos of the tear in photos 8 and 9. There are also threads coming out. The elasticity remains. How about trying it out...? Thank you.
