Thank you for viewing. Uniqlo Men's Black Socks Regular Length, Set of 8 ◆ Size All sizes fit 25-27cm Length approximately 19-20cm ◆ Color Black *Please note that the actual color may differ from the image due to lighting or natural light. ◆ Condition I used all 8 pairs for business use when wearing suits for about half a year to a year. I don't see any noticeable stains, but there is some fuzzing and pilling on the heels and toes. (The last two photos show the cleanest and the most pilled socks) Also, some of them have a slightly faded look. ◆ About the thickness of the fabric Slightly thick This is just my personal feeling, for your reference. They are not Heattech. [From the Uniqlo official website] ・The outer yarn is smooth and soft, and the texture is beautiful Supima® cotton. ・Added deodorizing function to prevent the smell of sweat. ・The heel has a three-dimensional wide heel structure, so it is less likely to slip and is comfortable to wear. ・The tapered line fits beautifully from the calf to the ankle by using a graduated knit. Product number: 414072 Material 84% cotton, 12% nylon, 2% polyester, 2% polyurethane Color: Black系 (Black series) Sock Length: Mid-calf to knee-length
