No price negotiations. Brand: SUGATA LABO Breathing Washi Socks (Pile Middle, Cobalt Blue, Size M) I accidentally purchased these. I opened the package but didn't use them and put them back. Material: Cotton Care Instructions: Machine Wash Materials or Fiber: Rayon 54%, Other Fiber (Washi Paper) 36%, Polyester 9%, Polyurethane 1% Size: M (25-28cm) Quantity: 1 Color: Cobalt Blue Pattern: Solid --- Product Details Top Highlights Excellent absorbency and quick-drying properties. Washi paper is lighter than cotton and has about twice the absorbency and about 1.19 times the quick-drying ability of cotton! It eliminates stickiness and stuffiness, which are concerns in the summer heat. Your feet get stuffy even in the cold winter, right? Cold feet are often caused by stuffiness, so washi socks are also effective for cold feet! Outstanding antibacterial and deodorizing effects. The washi yarn we use far exceeds the standard values for antibacterial activity in both JIS (Japanese Industrial Standards) and SEK (Certification Standards for Textile Products). This is the result of testing with isovaleric acid (the source of sweat and aging odors). Our washi yarn boasts a reduction rate of over 114%! Washable repeatedly. Our washi yarn allows you to wash the product in a normal washing machine. It is superior to general cotton products in both wash resistance and abrasion resistance. The frequently asked questions are, "Can I wash it?" and "Won't it dissolve in water?" You can wash it repeatedly, and it will not dissolve in water! You can just throw it in the washing machine! By knitting the washi paper into a pile, the heat retention is high, so it's warm in winter, and it's comfortable in the hot summer days because of its good absorbency!
