The high cooling effect of the compression beads and gel sheet intensely stimulates the acupressure points on the soles of the feet. The high-water-content gel (PAC-55), which absorbs plenty of moisture, and the "compression beads" attached to the sheet using unique technology, comfortably stimulate the soles of the feet like health sandals. Perfect size for the soles of the feet, providing a snug fit. Gentle on the skin and less likely to cause irritation. Contains five relaxing herbal ingredients (lavender, sage, rosemary, lemon, and orange). *Unopened, but will be sent without the box, contents only.
