All shimmers are not created equal.
Nicoletta shimmers are 100% edible and made from a mineral and added colourants.
Other shimmers claiming “food grade”/”food safe”/”non-toxic” are shimmers that are made of tiny pieces of plastic! Shock, horror! These terms are lingo used in the manufacturing of food contact safe plastics; these terms mean that the plastic touching your food will not leach harmful chemicals into it; however it’s not really your plan to eat this plastic/ attempt to pick it off your food! Look out for shimmers claiming to be food safe, and check for ingredients on the label (as required by law for food products).
