These socks are made using "Awa indigo" from Tokushima Prefecture, which has its origins in the Edo period. The socks are hand-dyed by indigo artisans in Tokushima Prefecture, using a distinctive tie-dyeing technique called "Muragumo Shibori," which results in a cloud-like shape after dyeing. *This product is an indigo-dyed product. Indigo-dyed products are treated to remove the tannins and to naturally fix the color after dyeing, but there may be some color fading or color transfer due to friction during use. Please avoid using this product with white or light-colored items as much as possible. The tannins may react with ultraviolet rays such as sunlight and discolor, so please store the product away from ultraviolet rays. If the product discolors, soak it in hot water overnight and wash it repeatedly. Since this product is hand-dyed, the color and pattern may vary from one to another. *This product has threads coming out from the seams between the patterns, but this is due to the characteristics of the knitting machine and is not a product defect. 95% cotton, 3% polyurethane, 2% nylon
