Our initial die cutter was able to carve out some pretty decent chipboard pogs to affix inventory stickers to; but we have since purchased a much better die cutter that cuts better discs. For a temporary view, we used our Inventory 1 set on the chipboard pieces, and a few of Paul Ooshun's Dungeon Buddies. The pog itself is a 1" diameter circle. As shown above, you can use 1" diameter circular stickers printed with your favorite characters and mobs. We also found:
they make a pretty spiffy base for miniatures too! So now, GM's can add a little twist to mobs on the encounter maps by adjusting what treasures they hold. Each collar holds up to 3 different chipboard pieces.
Now that we have the new die cutter, we have several protoype collars and pogs, it is time to make the multiple molds and the vaccuum chamber.
