I'm selling these armpit sweat pads that also function as cooling pads. I bought them this summer, but haven't had a chance to use them. I have opened the package, but they have been stored in a Ziploc bag and are unused (actual product: photo 6). They also come with a cover. For reference: https://www.makuake.com/project/snapcool/ Retail price: 4,400 yen Please consider purchasing if you are interested.
