MINERAL SHOWER Negative Ion Processing Manufactured by Kajii Woven Fabric Co., Ltd. Stored in the closet at my parents' house. New, unused items. One is unopened, and the other is opened but unused. ◆ Size: M Hip: 87-95 cm Flat measurement: Inseam 51cm ◆ Color: Beige According to the description: The material is treated with negative ions, which is said to have relaxing effects, fatigue recovery, improved blood circulation, and other health benefits. The texture is soft and smooth. The inside feels like it's brushed, providing warmth! I think you'll feel very warm wearing these♪ I would be happy if you could use them as regular inner bottoms for autumn and winter. [ Set of 2 ] Thank you for looking. #InnerBottoms #Women'sUnderwear #LongUnderwear #NegativeIon #ColdProtection
