The IMAK Eye Mask Pillow is a weighted compression eye mask made of soft, breathable cotton material. This stress relief mask soothes tired and puffy eyes while providing cooling relief. The IMAK Eye Mask Pillow was designed by an Orthopedic Surgeon, with massaging ergoBeads inside that create a gentle, soothing massaging effect around the eyes. The beads allow the mask to conform to the contours around the eyes, effectively blocking out light, while the unique stitching alleviates direct pressure on eyes. Made of breathable cotton material, the mask is comfortable to wear and is secured in place with an elastic strap. For added stress relief, place the eye mask pillow in the freezer to provide cool relief without the shock of ice or gel packs.
