Maintenance: Hand wash only to preserve the 3D structure and fabric quality. Many people try several sleep masks before realizing the real problem isn’t sleep — it’s light leakage. ringchan is a 3D blackout sleep mask designed for people who are sensitive to light and uncomfortable with flat, generic eye masks. Its contoured structure creates space around the eyes while sealing out light from all angles, including the nose area where most sleep masks fail. Why choose ringchan for your wellness routine? Will it block 100% of the light? Yes. The stealth nose wing (light-blocking flap) seals the gap around your nose bridge. It provides total darkness for meditation, yoga and midday naps, even when the sun is at its brightest. Is it comfortable for eyes and lashes? Absolutely. The 3D contoured cups create a protective vault. There is Zero Pressure on your eyelids, and your natural lashes won't touch the fabric, allowing for natural blinking. Will it feel hot or stuffy? No. We use Fresh Airy-Touch fabric with a breathable one-piece design. It encourages air to flow freely, keeping the eye area cool and refreshed during long flights or yoga sessions. Does the strap tug on hair? We designed a hair-friendly, adjustable strap. It is slim and smooth, providing a secure fit without the bulk or tension that ruins your hairstyle or causes temple pressure. Is it suitable for travel and office use? Yes. Its lightweight, minimalist design is perfect for professional settings. Whether you are on an airplane or taking a 15-minute power nap at your desk, it delivers instant quiet and darkness. Care Instructions: To maintain the 3D structure and soft feel, hand wash with mild soap and air dry. Avoid machine washing or high heat.
