I used this to help with my child's night crying, but it's practically unused (because I ordered the wrong size). It gets completely dark, like a blackout curtain. I bought it to use when I was struggling with night crying and early morning wake-ups. Includes three strong clips. * Size: 180cm x 280cm (when stretched taut) * Please understand that this item is stored at home and will be shipped with simple packaging.
