"MegRhythm" is a healthcare brand that supports the daily lives of people who want to live healthy and active lives. The brand offers products such as "Steam Warming Sheets" (general medical devices) that promote blood circulation and relieve shoulder and lower back stiffness with a comfortable steam warmth, "Steam Warming Eye Masks" (sundries) that envelop the eyes and eye area with steam at approximately 40°C, providing a relaxing feeling, and "Sheet Carbonated Gel Packs" (sundries) that refresh a feeling of fatigue and heaviness. Focusing particularly on the common complaint of "sleeplessness during hot nights," the non-woven fabric of the "Cooling MegRhythm Eye Mask" has been improved. By adopting a moisturizing, water-feeling non-woven fabric, the cooling power is approximately 1.3 times stronger (compared to our previous products), providing a more comfortable cooling sensation for stuffy, sleepless nights. Moving forward, "MegRhythm" will continue to propose moments of comfort that relax the mind and spread a sense of well-being throughout the body, not only through comfortable steam but also through products that offer a cooling sensation. ■ Product Features MegRhythm Cooling MegRhythm Eye Mask Comfortably cool even on hot summer nights when stuffiness is a concern – a refreshing feeling.
