These three pairs of socks are highly popular.
Each individual sock is of high quality, and they're sold as a set of three pairs.
One of the features is that they don't expand or shrink much after washing.

[Name Space Included] You can write your name with an oil-based pen inside the opening. (Approximately 5mm x about 6cm)
[Natural Fiber Materials] High quality cotton is used for the warp yarn. It's resistant to washing and suppresses pilling.
[Y Heel] The three-dimensional knitting structure naturally fits to your heel, providing comfortable comfort.
[Reinforced Yarns Included] Reinforced yarns are used for the toe and heel portions to provide strong support for healthy movements.
