Ordered 1 from Revain as a gift. I checked that it's easy to use (you don't have to wrap the headphone cords around anything "just right"), just wrap the headphone cords around your finger, slip them into your pocket, and let go. Did. It's supposed to be made out of cotton, so I feel like it can be washed on a gentle cycle and air dried or tumble dried low if it gets dirty for any reason. I wouldn't recommend heating as I assume the compression mechanism inside is not metal. However, the current Amazon price of over $8 is overpriced. I bought 4 more in "Staples" for HALF PRICE (and free shipping). They all made great gifts for colleagues this holiday season. If you're looking for a black headphone case, look no further than Essential Products. They are just listed with wrong description and item number (shows bag picture and charger name but headphone item number) which turned out when I ordered several.
