Ok, so here's the final product of doing all these chibis--It was my first time trying this out, and I think they came out pretty well. Each charm is 2 inches big with a metal key ring attached. They are plastic and sealed with a gloss coat, so they should be pretty durable. I've had Garnet on my keys for the past 3 days and he hasn't been scratched up yet!
I may or may not open slots for these. I'm thinking about getting a different type of key ring.
