Are the Albert Uster metallics edible?

Hi,

very late answer since i'm a new follwer, but no, it's not edible, food safe but non edibe.

just in case anyone else is looking for the answer.

No, it's not edible. 

"Food safe" would mean that something covered in it would be able to touch food, but NOT be eaten.

This tutorial by Liz Marek is very helpful in identifying "edible" metallics:
