Thank you for viewing! For those who wear out socks hard every day at work or club activities, here's a superお得な 20-pair set. 【The biggest merit of this set】 "All the same color and same size!" Even if one sock gets a hole, you can still use it by pairing it with another one. There's no waste of "one sock left and goes to the trash"...! • Contents: 20-pair set (40 socks total) • Color: Dark gray (close to black) You can compare it with black in the first photo. • Size: 25-27cm (men's free size) • Condition: Brand new, unused Recommended for: • Workers and those in on-site jobs who get their socks heavily soiled with mud and friction every day • Students in club activities whose socks wear out quickly due to intense practice • Those who find it troublesome to "find pairs" after washing (just grab two at random and they'll be a pair!) We do not sell individual pairs, but we have set the price accordingly. If you want to save money on consumables, why not consider this?
