These are UNIQLO leggings, a collaboration with Meguru Yamaguchi. I used them for hot yoga, etc., but I'm selling them because I no longer have the opportunity to wear them. There are no noticeable stains, but there is some pilling on the inside, as shown in the third photo. The outside is a smooth material, so it's in relatively good condition. I think they can still be used. However, please check the photos for the condition before purchasing, as these are used items. I will fold them up small for shipping. #UNIQLO #MeguruYamaguchi #collaboration #blue #leggings #yoga #pilates #strengthtraining #exercise
