MegRhythm Releases Limited-Edition Sanrio Characters Design Steam Eye Masks on May 30, 2026

Kao Corporation's healthcare brand, MegRhythm, will release a limited-quantity series of its "Megurism Steam Eye Mask" featuring Sanrio characters on May 30, 2026. The collection will showcase three designs: Hello Kitty (unscented), Cinnamoroll (grapefruit scent), and Pompompurin (neroli scent). Timed for May, a month when life changes can disrupt sleep patterns, the special packaging depicts the characters peacefully drifting off to sleep. The eye mask gently envelops the eyes with ~40°C steam, providing a warm, relaxing sensation that lasts for about 20 minutes to help improve sleep onset. The product has also earned a Gold certification from the Sleep Healthcare Council for its sleep support function.
