My family, who loves online shopping, bought this, but they're too lazy to use it, so I'm selling it while it's still in good condition! The main body looks almost unused and is in good condition, but the instruction manual and box have some signs of wear, including creases and a few tears. [Fukutsuji-style Pelvic Shape Pillow DX] Color: Red Size: 44 x 21 x 15.5 cm (approx.) Materials: (Outer fabric) Nylon, polyurethane (Back, sides) Polyester (Core) Polyurethane, steel Product Description: Simply lie on the Pelvic Shape Pillow DX, arch your back to stretch your back muscles, and gently sway. This loosens the stiff muscles around the pelvis and positions the muscles around the abdomen correctly. The two pressure protrusions on the outside and the six point protrusions on the inside gently massage the muscles around the pelvis.
