D20 Aquarium Decoration

[cade]

Hey, do y'all have any idea whether a D20 like this would be aquarium safe? I've tried asking the sellers what exactly it's made of, but their contact page isn't working (at least for me).

Has anyone used dice as aquarium decor? Is there something you look for in dice to indicate they're aquarium safe? Anything to avoid?

Thanks

Why don't you try putting it in purified water, then sending the water to a lab after a week to test if anything leached into the water.
