Here's Lilith the Firehawk from one of her "introduction" screens in Borderlands.
These magnets are 1/8" thick alder wood, just under 3" x 2". The design is created then laser engraved and cut. A few coats of spray lacquer are applied to protect the wood, then a polyurethane blend is brushed on to improve the texture of the piece. After all finish coats are dry the magnet is affixed to the back.
You'll find LOTS of additional Borderlands goodness in other shop listings.
