Set of 2 Colors: Off-white, Pink Size: F (Length approx. 28cm, Width approx. 27.5cm) Special knitting that absorbs sweat and oil on the surface (natural material "cotton") and creates friction to generate more negative ions. Because it's thinly knitted, the fabric is thin and stretchy, fitting the body comfortably and feeling gentle♪ Teijin Teviron is a synthetic fiber developed by Teijin Ltd. and has excellent features. ◎ The material itself retains heat without letting it escape, so it has good heat retention. Protects the body from the cold of winter and the chill of air conditioning in summer. ◎ Generates the strongest negative ions among all fibers through friction with the skin. Negative ions are said to prevent blood oxidation and are good for the body. Although it is new, please refrain from purchasing if you are concerned about storage at home. #Teijin #Teviron #NegativeIons #SetOf2BellyWarmers
