Genialt palett for de som ikke har så mange glitterskygger fra før av. Lettest å påføre med en finger for å få mest ut av pigment og glitter. Noen av fargene drysser litt hvis man ikke er forsiktig. Flere av fargene kan kombineres sammen, men jeg bruker alltid matte skygger som base i globalen først.

Research indicates that the bioavailability of heavy metals may be lower in plant- derived foods than in animal-derived foods, despite the fact that plant foods sometimes contain higher amounts. This is likely the reason why vegetarians had lower levels of cadmium, lead and mercury even though their heavy metal intake was .
