Do what it is, the plastic back looks a bit "cheap" from.
IVSO Slim Smart Cover Style Leather Folio Case Folio Case Cover for Apple iPad 2 Tablet PC Air (For Apple iPad Air 2, Smart Cover-Blue) (Electronics) 3
I bought the cyan / white version for my iPad Air 2. With the functionality (magnetic closure, fitting accuracy, accessibility of the keys) I am fully satisfied. Also I like that the lid is firmly secured to the back (cover, which were attached with magnets were always too uncertain). However, the white plastic, from which the bottom is made, acts a bit cheap. So an iPad happens to be a "fashion Accesoir". And you do not want to disfigure its casing yes.
