Kohshin Rubber Kraizer ZK-01 - Color: Black - Size: 27cm - Sole: Non-slip sole - Material: Waterproof material Thank you for viewing. I used these for about 30 minutes after purchasing them new. There are no stains, tears, or odors, but there are minor scratches from use. To keep the shipping size to 80cm, I will pack them compactly in a cardboard box, so please understand.
