【Warm and Gentle with Far Infrared Yarn】 Far infrared yarn stores heat, keeping warm air in. By warming the wrists, it keeps even the fingertips, which tend to get cold, nice and warm. 【Skin-Friendly Silk Material】 The inside is 100% natural silk. The soft and smooth texture unique to silk spun yarn makes it comfortable even for long hours of wear. 【High Elasticity for a Secure Fit】 The cuffs have supple elasticity, reducing tightness and providing comfort. It doesn't slip easily, allowing for comfortable wear even during work. 【Gentle Support with Light Compression】 It gently fits the wrist and provides support with moderate pressure. It's more comfortable than a supporter and doesn't leave marks, which is a nice point. 【Size｜Materials｜Country of Origin】 Size: free Length 22cm Width 9cm Surface: Acrylic 80%・Nylon 15%・Wool 5% Lining: Silk (silk spun yarn) made in JAPAN #Made in Japan #Silk #silk #silk #Far infrared #Hand warmer #Sensitivity to cold #Warmth activity #Wool #wool
