The film rear Smart cover from U-Bop is an ultra-thin piece of protective film exactly cut to cover the rear of your iPad & allow your official magnetic Smart Apple flip, to be attached & used. The film is clear, has a Matt finish to the outside & a sticky self-adhesive finish on the inside, which sticks to your iPad. This leaves no residue if removed. The film is so thin it can be used underneath an existing case you may already have as an added level of protection, it really is great. The film has five cutouts to allow further access to all features on the iPad. It also has cutouts at the corners meaning it can be curved around the outside of your iPad tablet.
