Set of 3 underwear. This is a combination of thick material and heat-generating material. These were used daily, so the size is marked as 90, but I believe they have shrunk slightly, so I've listed them as size 80. Please purchase if you understand that these are used items and will be simply packaged. - Size: 80-90cm - Material: 100% cotton - Design: Striped - Quantity: Set of 3
