It looks like the lenses suit the looks of the premium exterior of the iPhone 5/5S itself. Although the parts that attach the Olloclip macro lenses to the device are made of soft plastic material, they don't look cheap. According to the manufacturer, they fit securely and don't harm the device. On the other hand, the barrels of the lenses are made of the more premium aircraft aluminum and the optical parts of the kit are precisely ground coated.
The Olloclip macro kit is compatible with the iPhone 5/5s, but works with the 5th generation of the iPod Touch as well. The set, which is available only in black at the moment, can be ordered directly from the manufacturer's site and is priced at $69.95 (a link is provided for you at the source).
