can somebody update me on these kind of chips.
I first thought they were made out of clay.
The chipco chips are hard, don't bend much but brake.
But they drill nice and when burning they don't burn up like plastic.
Yes, I know some people are saying why the hell are you burning chips?
It are some of of the ten thousands roulette chips (SBM) I'm testing.
The quality is so poor and the numbers available are so high that I just wanted to test them.

Thanks for reading, looking forward reading the answers!
