Tokens for Alchemists boardgame

I got an early print run of Alchemists, and the tokens are a little oversized and were hard to put in and take out of the deduction grids.

These are what I used to make more.

You can see them painted up in the token tray I made for the same game here:

All of the tokens in the game are colored versions of + on one side and - on the other except for the nullification ones which are the cancel symbol on both sides.
