These are reversible counters with a +1 on one side and a -1 on the other side, suitable for Magic the Gathering or similar card games, or any board games really.
The raw print - White Strong & Flexible
Close-up showing the groove around the center, this serves as a guide if you want to paint the two halves different colors.
Close-up of the Alumide print - it's really crisp and has a slight metallic sheen.
Painted with black acrylic - they look great stacked as you can easily count them.
Close-up of the painted tokens.
Close-up of the -1 side.
I painted the numbers of the Alumide tokens to distinguish the two sides.
Here are the paints and inks I used.
The White Strong & Flexible is really fun to paint - you just dab the brush inside the numbers and it bleeds all the way to the edge on it's own. I used a size 1 brush, slightly damped with water. Here's a short video: https://vine.co/v/hwKqPO9wWhD

They're also available in colored sandstone, with the black & white colors pre-printed, however I haven't ordered this material yet so I haven't got any photos of it.
