This is a set of 11 warming eye mask pads. I'm selling them because I lost the eye mask and have no use for them. - Warming effect: Approximately 40°C for about 20 minutes - Contents: 11 packs (for 11 uses) Please note that the item will be shipped in simple packaging. If you have any questions, please feel free to comment (^_^;) Due to the irregular nature of my work schedule, I've set a longer shipping time, but I will do my best to get the item to you as quickly as possible (^^)
