【Certified in Japan, 99.99% Light Blocking Rate】 The most important role of an eye mask is "blocking light." In modern times, small lights from charging devices and standby power can be noticeable in a dark room. It's difficult to achieve complete darkness just by turning off the lights, and even if you do, your eyes can adjust and start to perceive light after a while. When choosing an eye mask, it's important to consider the light-blocking rate. 【Ergonomic 3D Structure, Comfortable to Wear】 The 3D structure reduces pressure around the eyes and is lightweight, making it comfortable to use. For working adults and travelers who want to recover their energy with a short nap, an eye mask is an essential sleep aid. Instead of ear loops, we use a headband type, and both the adjuster type and Velcro type allow you to freely adjust the tightness to your liking. 【Carefully Selected Materials for Long-Lasting Comfort】 When used at night, you'll be wearing it for a long time, so it's recommended to choose a material with high breathability as well as light-blocking properties. It's a washable material that can be hand-washed, so you can keep it clean throughout the year with regular care. 【Eye Relief, Rest】 Recently, with the increase in working from home and time spent at home, the use of smartphones and computers has increased, and more people are experiencing eye fatigue. Wearing an eye mask blocks out light, allowing you to rest properly even during short breaks and give your eyes a rest. 【Refresh During Travel or Spare Time】 Comes with a convenient carrying pouch, so you can relax anywhere... A useful item when you want to take a nap at the office or take a short daytime nap. For busy modern people, "getting good quality sleep, even if it's short" is very important. Why not try incorporating an eye mask? 【Product Size】10.5 x 23.5 x 1.5 cm (Black - Adjuster) No discounts #3D Eye Mask #Eye Mask
