It seems like the blue and gray ones haven't been worn. The white one has some slight pilling on the inside, suggesting it's been worn once or twice. Please refrain from purchasing if you are concerned about this. The size isn't indicated, but I tried them with a 25-27cm tabi sock, and they were almost the same size. A set of 3 five-finger knit socks in various colors. - Colors: Blue, Gray, White - Design: Five-finger socks - Material: Knit - Quantity: Set of 3 Thank you for viewing.
