QUWOLACE is a 3D memory foam sleep mask designed for people with lash extensions who want a more comfortable way to rest when light interrupts sleep.
Light from a room, a journey or a shared sleeping space can make it harder to settle. This mask is made for rest at home and on the go, and can also be worn while concentrating or meditating. Its contoured shape and adjustable strap make it a practical option for people who want an eye mask with room around the brow area rather than a flat cover across the eyes.
The hollowed 3D design leaves extra room around the eyebrows, while the higher, deeper nose cutout is designed to sit comfortably across different face contours. That contoured construction is relevant for lash extension wearers looking for an eye mask shaped with space around the eye area. The mask is intended for both men and women.
Yes. The elastic head strap is adjustable, so you can set its fit for wearing during sleep, concentration or meditation, including yoga. The strap is described as soft and designed not to move or fall off while you sleep. The memory foam is low-rebound and ultra-soft, giving the mask its cushioned feel.
Use it at home or while traveling by flight, train or car, and when camping or elsewhere that light disturbs your rest. For care, hand-wash with water below 40°C (104°F), then let the mask dry naturally before wearing it again.
