These made-in-Japan eyemasks create a blissfully warming temperature of 40 degrees Celsius (100 degrees Fahrenheit) - the same warmth as a nice hot bath. The heat relaxes your eyes and, by extension, your whole being, for a full 10 minutes or longer.
Other varieties of eyemask also available: Unscented, Yuzu Aroma, Chamomile & Ginger Aroma, Lavender & Sage Aroma.
