This is a set of three pairs. The size is 25-27cm. I bought them new and used each pair only once or twice for a short time. However, they didn't fit me well, so I'm selling them while they're still in good condition. There are no pills or frays, and the non-slip rubber on the soles still has good grip, but since they are used items, please understand that they are non-returnable and non-refundable. A set of 3 pairs of colorful socks with non-slip grips. - Color: Orange - Color: Green - Color: Black - Features: Non-slip Thank you for looking.
