These are numbered miniature base markers I made to use with printed miniatures for the boardgame gloomhaven. I printed them in white to represent the standard monsters. An elite marker, printed in yellow, can be snapped into the base to indicate an elite monster.

I chose to use numbered rings instead of attaching/modeling in numbers to each mini permanently. We'll see how this plays out. I've also included an unnumbered base ring in case you want to use stickers, per request.

Update 2018-01-20: Added improved V2 version that fit 25mm bases a little better and clips in the elite markers better as well. 

The base rings were designed to fit the base collections made by Eli Owens, see a sample below. As such they are sized to fit a 24.5mm base. They could easily be scaled to fit a different sized base.
