I've used this a few times, but I couldn't use it properly and it's been stored away. There is no instruction manual, only the main unit. I couldn't fold it properly and stored it folded small, so there are creases. Please be aware of this if you are concerned. Please note that it will be shipped compactly. Due to the shipping costs, I am not considering any further price reductions, so please understand. This is a doctor-supervised dome-shaped sleep aid that blocks light and supports comfortable sleep. - Model Name: IGLOO Sleep Dome to Wear - Features: Doctor-supervised sleep dome - Uses: Perfect for naps and light protection - Color: Blue - Design: Dome-shaped Thank you for looking.
