This item is new, but I couldn't determine the size, so I tried it on, but it was too tight, and I gave up. I think it's about a women's M size. Measured flat: Thickest part at the top: 11.5cm Narrowest part: 8cm Home cleaned. It's old and has been stored for a long time, but there's no damage, and it has a strong compression. Please understand that this is a used item. Please refrain from purchasing if you are sensitive to used items.
