Some iPhone cases that feature One Direction include the officially licensed One Direction snap-on case in denim for the iPhone 5C, and the Music & Singer Series hard case for the iPhone 4 and 4S. Both cases are available on Amazon as of August 2015.
The officially licensed case features a denim background with five white diagonal stripes, each of which holds a head shot of one of five One Direction band members. It also features the 1D logo in red. The Music & Singer Series case shows five greyscale portraits of the band members side by side. Both cases utilize a protective hard shell design with snap-on functionality.
