These are condition tracker rings or condition markers. Great for Dungeons and Dragons, Pathfinder, and other tabletop RPGs. I printed them in different colors to make it easier to tell them apart. I tried to make the colors as intuitive as possible. Matt Mercer, the DM on Critical Role, uses condition rings similar to these. Make a great gift for your dungeon master and sure to be a big hit with your players if you are the DM.
