Other Info:
This Companion Cube 'bead' is made out of rhodium plated sterling silver, with pink enamel hearts. It's designed to be worn as a charm on a European-style charm bracelet.

Technically, this charm could be thought of as one from a set of ten beads/charms, which were all made available on the ThinkGeek website at the same time. This is the only Portal-themed charm in the set, however.

Designed and available exclusively through ThinkGeek.
