I'm selling these because I didn't use them, even though I used two. These are eye masks that relax you with approximately 40°C steam, and come in a pack of 5 for a comfortable experience. I will ship them by Yu-Packet Post Mini after taking them out of the box. - Brand: Megrhythm - Product Name: Steam Eye Mask - Quantity: 5 masks - Temperature: Approximately 40°C - Usage Time: Approximately 20 minutes - Manufacturing Date: May 19, 2021 Thank you for looking.
