◯ Stimulate acupressure points, meridians, and lymph nodes to relieve scalp stiffness! Stimulating the acupressure points on the head can relax the whole body. Easy to use: Simply put your hand through the band on the back and roll it along your head. The 7 stainless steel balls comfortably stimulate acupressure points and rotate smoothly 360 degrees, designed to avoid tangling in hair. It uses a soft, flexible material (elastomer resin) that fits comfortably in your hand. It fits snugly on all kinds of uneven surfaces, so it can also be used for body, face, scalp, upper arms, thighs, and buttocks massage. ◯ Palm-sized, so you can carry it and use it in various situations. I have used it a few times, and it has been disinfected with alcohol. There is no box. ◯ Overall, it is in good condition, but there are some faint scratches in the areas marked in the photos. Please check before purchasing.
