This very niche print is designed to solve a very specific problem I have.
Maybe you have it too.

When painting miniatures, I've started to use my thumbnail to check the opacity and amount of paint on the brush.
So this is a substitute for that.

There are three sizes and two design variants.
The sizes of the rings are 2, 2.25, and 2.5 cm in diameter.
The palette is either centered on the ring or its edge.
The pallette is 3x3 cm on all rings.

Each ring has its own plate so that you can pick and choose.

Try it out and see what suits you best.
