Proporta has introduced the Carabiner Crystal Case, a new protective case for the second-generation iPod nano. Made from the same type of polycarbonate plastic used to make protective eyewear, the case is said to be shatterproof and shock absorbent, and allows you to see the screen through the case’s clear design while also providing cut out access to all ports and controls. The case is made of two parts which slide together, and comes with a carabiner clip.
