I had the pleasure of meeting a lot of people at Blizzcon this year, including a married couple from Truckee California that runs Gamingpins.com. They happened to be outside taking a break from demo units and crowds when we crossed paths and got to talking. They had messenger bags just loaded with really cool Diablo pins and I had to know where they got them. Turns out, they made them!
Very intricate designs and throwbacks even to Diablo 2. You can check out their full line of Diablo Pins, along with their other Blizzard franchise sets at their Etsy store(link below). I also pulled a shot from their site showing off the Sanctuary-centric ones. The Baal one is especially cool. What do you think?
