IGLOO Sleep Pillow to Wear Feels good even for a short time. A dome developed by a sleep specialist for your quality sleep. Covering the face area creates a moderate sense of enclosure, allowing you to sleep comfortably. This product's dome features a special structure that blocks light and sound. It has a higher sound absorption rate than general urethane, and when you enter the dome, you'll experience a quietness as if your ears are gently covered, like wearing soft earplugs. Furthermore, the dome structure incorporates an aluminum sheet to achieve ideal quietness. The light-blocking rate is 99.9%. This allows you to sleep soundly without being bothered by the brightness of the TV your family is watching. There are some light stains in places, so please understand this before purchasing. Please refrain from buying if you are sensitive. Thank you. Will be shipped folded.
