Custom Brass Bell Tortoise Shell Keychain Pendant - Retro High-End Car Lanyard

It's really tiny, the button for the loop is an unattractive black color (in the photo it's gold), I haven't been able to pull the loop onto the button yet. The thread on the container is very tightly ground with the gasket. And what is this colored sand in the bag?

It looks much more interesting in the photo than in real life.
