Soothe tired, puffy eyes with the help of the Bathefex reusable Gel Eye Mask with adjustable head strap. Cooling gel beads help reduce swelling and reduce dark circles. Reversible design - use the gel bead side to reduce swelling and puffiness, or the plush side for a gentler, more relaxing experience. Place Gel Eye Mask in the refrigerator for 1 hour or in the freezer for half an hour to cool. Once cooled, place gel eye mask onto eyes for 10-15 minutes.
