Tokens are made with a 16mm glass, and have felt applied at the bottom.
I have some designs available and do make custom houses as well.
You can check it here:
The price is 5€ for each 8 power tokens pack, so you can combine 2 different houses in order to play BANNER agendas
You'll have the Power Tokens in Stahleck ready to use them
If you want tokens for a different game, just ask me!
