I used it once to try it out, but I'm not using it, so I'm selling it. Since I haven't used it much, I think the condition is good. It will be shipped folded, so please purchase it if you understand. Product Name Sleep-in Pillow IGLOO(A) Sleep Dome Materials Cotton, urethane, polyethylene, aluminum, PET Size Approximately Width 72 x Depth 55 x Height 36cm Weight Approximately 780g Color Navy Specifications This sleep dome was developed by a sleep specialist. By covering the surroundings, a moderate sense of enclosure is created, allowing you to feel comfortable and calm even in a short amount of time. At first glance, it may seem cramped, but it doesn't feel enclosed because it has depth. Just put in your pillow and it will quickly transform into a sleep pillow.
