"Poplocks are a very clever system for making movable papercraft fastenings with die-cutting and folding. The Paper Pose-Ables site has a bunch of downloadable papercraft toys you can print out and make, as well as pre-cut/scored kits you can buy, for making fabulous poseable robots and other cool figures. .. the Poplocks system really makes for a great, semi-rigid joint for the toys."
