TOTALLY BLOCKS LIGHT - While most eye masks on the market let light pass around the nose, we are proud to offer a revolutionary new design that solves this problem, with one that hides the wings of the nose and which eliminates any exposure to light. No matter where you are - in bed or on a bus - the total darkness offered by our eye mask will allow you to enjoy a deeper, healthier and trouble-free sleep. Compared to traditional eye masks , the 3D outline is more spacious, which is essential for sleep. But the sleep mask takes it one step further by also adapting to users wearing eyelash extensions. BREATHABLE WITHOUT PRESSURE - Thanks to its unique porous structure, the agglomerated foam covering the mask not only allows your eyes to "breathe freely", but also offers a natural and pressure-free fit. In addition, the skin-friendly elastic polyester outer layer is anti-dust mite and anti-bacterial and does not wash off. The strap used on the sleep mask is very elastic, with an adjustable fastener. The mask can therefore be adjusted to accommodate a wide variety of face shapes and sizes, for children and adults alike. Washing Instructions: 1. Hand wash, 2. Water temperature below 40 C (104 F), 3. No ironing.
