I created these meeple tokens for my son's Star Trek Adventures games. Colors needed are gold, black, white, silver, yellow, red, blue. Silk for the gold and silver looks great.
The gold base is meant to be used for Ensign, Lieutenant, Commander, and Captain ranks, while the black/gold base is for the Lieutenant Junior Grade and Lieutenant Commander ranks.
Press the top into the bottom base. Glue can be helpful, but wasn't necessary for mine.
