Last time I ordered 6*10gr jars and 8*5gr jars with sifters, 32! lipbalm tubes (!) and a lot of samples and some 1 ounce-powders and they managed to fit it into a flat-rate-envelope!
The samples are cheap and generous so just pick a few different that you think you´ll like. The only one i really didn´t like were Chameleon, wich is strangly red-browm-lilac with blue green sparkles... I have never seen so much sparkles but it´s very hard to find a use for it. Anyway I´ve done some blue shade were I´ve added some of it and that actually works....
