Look at the top of the page, Stylin Online. Though the matrix it's self is a very crappy bendy rubber... I had one in hand at Gencon where they had a booth, and I wasn't impressed. If it were a solid plastic, or metal, I'd be sold.
The New Years Convoy one is metal. I've always been after these ones as well though. Only ever seen them for sale twice and passed up because they were too expensive both times.
