Those prices are obscene for edible, gum arabic based glitter

You can find the same, if not larger, selection for 1/3rd the price at:

DON'T USE THE NEW RECIPE RECENTLY POSTED, THOUGH.
That recipe suggests baking granulated sugar with liquid color added to it. It's a complete waste of time. All you need to do to get "that" product is to mix gel/paste color with granulated sugar in a zip top bag and rub it around until the color is well mixed. There is NO need to bake it.

This recipe works for metallic glitter:

This recipe works well, too. Add color to the water.

50 ML (10tsp)HOT WATER
25 G ( a scant 1 ounce ) GUM ARABIC

1. POUR WATER INTO A BOWL AND SPRINKLE GUM ARABIC OVER. STAND THE BOWL IN HOT WATER, STIRRING GENTLY TO DISSOLVE.
2. STRAIN MIXTURE THROUGH A PIECE OF NYLON. BRUSH MIXTURE ONTO A CLEAN BAKING TRAY OR GLASS SURFACE AND PLACE IN A WARM OVEN (140C or 275F) UNTIL DRY.
3. BRUSH OR SCRAPE THE DRY GLITTER OFF THE TRAY AND CRUSH IN INTO FINE FLAKES. STORE THE GLITTER IN AN AIRTIGHT JAR.
