I usually purchase it for wearing purposes. I bought it three times until now. When socks are bought one pair at a time by another feeling at that time, if one side is lost or only one hole is opened, both of them can not be worn and waste will come out. So if you continue to purchase exactly the same thing, it is reasonable without such waste. For such a reason, I tried choosing this product, but I am generally satisfied. Although it is silk but its eyes are coarse, it is not a smooth feeling, but comfort is not bad even in the summer. In terms of durability, I feel that the toes and the heel portion are easy to pierce a little, but I think that this is enough durable as this price. If you give a request to the manufacturer, I think that you want to further strengthen your toes and heel parts even if you upgrade prices a bit.
