ReFa 4 CARAT RAY is an advanced Japanese beauty massage roller engineered to deliver professional-style kneading care for both face and body. Featuring four multidirectional rollers arranged at precise angles, it effectively grips and kneads the skin vertically, laterally and superficially, closely mimicking esthetician hand techniques. An enlarged solar panel embedded in the ergonomic handle generates soothing microcurrent from natural light, enhancing circulation support without batteries. The platinum-coated rollers and waterproof construction meeting JIS IPX7 standards ensure durability and versatility, allowing use during bathing or daily routines. Authentic Japanese design and craftsmanship make it ideal for refined self-care and contour care at home.
