This is a rechargeable hot eye mask. It can be used about 3 times on a single charge. It heats up quickly, so I think it's easy to use. A charging cord is included. A charcoal pouch is also included. I apologize, but there is some staining on the back, but if you don't mind that, I think it's perfectly usable. I purchased it for around the 3000 yen range. Thank you for looking.
