This is a pocketable down muffler from MUJI. The color is beige. Purchased in October 2025. Used for about 2 short days. I bought it to use while reading before bed. I have not used it outdoors or while eating or drinking. There are no noticeable stains, but upon close inspection, there appears to be a stain on one end. (Photos 7-9) It is not certain whether it was there originally. It has been home-cleaned with a detergent for delicate clothing. Please consider this item, understanding that it has been washed and stored at home and is used. Size: Approximately 100 x 26 cm It will be shipped compressed. ☆Please check my profile.
