Handmade item. These are thick, incredibly warm socks created by Mr. Inotani. They are made with Opal yarn, cashmere, wool, and alpaca, making them very soft and warm. Size: 23 (large) Wool Alpaca Cashmere 100% (2 strands) Opal yarn (wool 75%, polyamide 25%) These are warm, extra-thick socks knitted with multiple strands of yarn. I do not use yarn from 100-yen shops. I use about 3 to 4 strands of yarn. This time, I used: Two types of high-quality German Opal yarn Avril cashmere Alpaca Wool I use a lot of yarn, and it takes a lot of effort to knit, so I can't make many. However, I want to offer them at a reasonable price. They are knitted three-dimensionally to fit the shape of the foot, following the arch and ankle curves, so they fit snugly without slack. They don't have the constricting elastic materials found in commercially available socks, so they don't restrict blood flow. The moisture-wicking properties of wool reduce stuffiness and chills from sweat, making them recommended for those who feel cold easily. They are also recommended for mountain climbing and camping. You should feel almost no itchiness. I use 100% natural materials like wool and cotton. I do not use yarn from 100-yen shops or cheap yarn. Care instructions: Wash in a net and dry in the shade. Do not use a dryer. Since cashmere yarn is used, it may shrink and pill after about a year of use. However, they are still warm, and since they are made with high-quality yarn, I hope you will take good care of them. All yarn ends are woven in multiple times, so even if a yarn end comes out, you can cut it. I do not accept claims regarding unraveling. Due to the thickness, they will be packaged in a zip-lock bag and compressed for simple packaging. Gift wrapping is also available.
