Nayoya Back and Neck Pain Relief Acupressure Mat 16” x 26” in Like New Condition This mat is used for acupressure; one lies on it to give relief from pain and stimulate acupressure points.

The mat is soft and pliable, easy to fold up and carry, the points are of medium pressure. -Smoke-Free Home -Next Day Shipping -Highly-Rated Reliable Seller -POSH Ambassador -I consider all reasonable offers, but only if you send them😉
