RAKUNA Brand Shoulder Blade Release Pillow Thank you for viewing. This is the RAKUNA brand massage pillow, designed to relieve shoulder stiffness by stimulating the shoulder blades and surrounding muscles with 18 protrusions and a curved shape that supports the back. The reverse side allows for a pose that expands the chest and straightens the back. I purchased this on Amazon last year, but I'm selling it because I've barely used it, only trying it once or twice. The item is just the pillow itself, without the box, so I will wrap it in cushioning material for shipping.
