Our wallpaper is made from a woven fabric, which may expand and contract with temperature and humidity changes during shipment. This can result in the rolls appearing wrinkled or creased upon delivery, however, these folds are not permanent and will not appear once wallpaper is smoothed out and applied to the wall.
If you are you concerned at all about your shipment, send us an email at hello@yellowpop.com with photos and we'll do our best to assist!
