Not only is it stress-free, but it also features a thin heater and weighs only 74g, making it ultra-lightweight! You can relax without any unnecessary irritation. ・Two-level temperature adjustment & auto-off timer "Adjusting the temperature with a remote control is a hassle..."

There are two adjustment modes: "High" and "Low." The core temperature ranges from 38 to 50 degrees Celsius, warming you deeply in about 10 minutes.
