That's basically how I feel about it...I think it looks pretty but I imagine working with it would be rather messy, and I too just can't imagine biting into it! If it was on frosting for decorative purposes I feel like I would be picking it off and not eating it...defeats the purpose of edible glitter then, doesn't it?!
Its not messy at all. Plain glitter sprinkles look like clear pieces of plastic, although they are edible.
You sprinkle them with your fingers or out of the jar, like regular sprinkles. They are pretty much weightless, and you have to sprinkle them on something thats still "wet" in order for them to stick. They will melt though, if the frosting is too wet.
They are tasteless and you can't even feel them or even know you are eating them.
For a test trick tip......
sprinkle a little bit of the edible glitter on a plate, just a little bit.
Lick your finger, and press it onto the sprinkles on the plate.
Then lick your finger.
You will see what the "feel" is.
