Please comment if you wish to purchase in bulk. - Brand: GUNZE - Model: CK9013N - Size: XL (LL) - Material: 100% Cotton - Design: Crew neck - Color: Skin Beige - Retail Price: 1430 yen (tax included) *Reference from Amazon 1. Washes clean even with just water, comparable to using regular detergent. 2. Higher moisture absorption and faster sweat absorption than regular cotton, controlling stuffiness inside clothes for a refreshing feel. 3. Effective against difficult-to-deodorize ammonia odors and components that cause sour sweat odor. Deodorizing effect against sweat odor lasts even after 100 washes. *Deodorizing effect may vary individually depending on body type, etc. 4. Made gently without excess tension on the fabric from knitting to sewing, in a relaxed state. Less shrinkage after washing due to the absence of residual tension in the fabric, and compatible with clothes dryers. 5. Reduced irritation from laundry tags by using transfer printing for laundry care symbols. Thank you for looking.
