This is a red color shoulder blade release pillow. It helps with stretching and relaxation around the shoulder blades. The protruding parts fit the shoulder blades and back, providing a pleasant stimulation. ★ There are cracks visible on the protrusions, but I believe it can still be used. I am very sorry, but please purchase only if you can judge from the photos. (I try my best to show them, but there may be some scratches that I couldn't capture. Please understand this as well before purchasing.) It is also sold on other sites. Please note that it may be sold out. Main Specifications/Features Shape: Ergonomic V-shaped (or heart-shaped) design. Designed to fit the curve of the neck. Protrusions (acupressure points): * Large protrusions stimulate the muscles at the base of the neck and the back of the head (suboccipital muscles). Small protrusions stimulate the surrounding muscles with point pressure, giving a feeling like acupressure. Material: Polyurethane (PU) foam is used. It has moderate elasticity and uses your own weight (the weight of your head) to achieve an acupressure effect. Size: The width is about 20cm to 25cm, and it is compact enough to carry around. How to Use Place it on a flat floor or bed. Lie on your back slowly so that the protrusions hit the areas where you feel neck stiffness. Relax for a few minutes (the guideline is about 5 to 10 minutes a day) while feeling your neck being stretched by your own weight. By slowly shaking your head left and right, you can also get the effect of the protrusions massaging the muscles. Precautions Avoid long-term use: Start with about 5 minutes at first, and don't overdo it (it can cause muscle soreness). Not for sleeping: It is not a pillow for sleeping, so be careful not to fall asleep while using it.
