On the Go iPhone 5s case. Some people need a pen to fully express. This iPhone 5 case keeps a cult classic CARAN d'ACHE 849 writing instrument as near as your iPhone. The fine finish and bright colors of the pen command all the attention, as the 3D printed case blends into the background. Features: Also holds 2 to 3 credit cards. Does not shade the lens or the flash on either the 5 or the 5s. A great gift for people who like things kitted and ready to go.
