The Huggaroo Gem hot and cold eye mask is versatile and comfortable. Enjoy it as a warm compress for headache relief, migraine relief, stye treatment, chalazion treatments, or dry eyes by inserting the patented microwavable heat pack within it. The unique silhouette of our insert was designed with your ultimate comfort in mind. With or without heat, the Huggaroo Gem can be enjoyed as a weighted sleeping mask with the hot insert in place. Alternatively, use the included custom gel ice pack to soothe a migraine, for tension headache relief, dark circles under the eyes, or puffy eyes. This model features subtle lavender aromatherapy; an unscented version is available as well. One size fits all. These eye masks are filled with natural lavender flowers and flax seeds. When you open the package, you may see a small amount of crumbled flowers that were shaken loose during shipment.
