Thank you for viewing. This is a set of two M-size Vantelin & Three Runner knee supports. The Vantelin Kowa breathable knee support has a breathable mesh structure, and the U-shaped taping structure supports the knee by lifting the kneecap. The Three Runner knee support is made of fibers that are gentle on the skin. It is a product with excellent moisture absorption and durability, and is also resistant to friction. It is highly elastic and can be firmly secured. I have worn these as knee supports about 20-30 times since purchasing them. They no longer fit me, so I have stored them after home cleaning. There are no noticeable scratches or stains, but there are some wrinkles and signs of use. The size is M, with a knee circumference of 34-37cm (Vantelin) and 31-37cm (Three Runner). Please check the product condition in the images. We appreciate your purchase if you understand that these are used items. - Brand: Vantelin / Three Runner - Color: Silver Gray / Black - Type: Knee Support - Total Length: Vantelin approx. 25cm / Three Runner approx. 16cm
