Initially, purchased the essentials face brush kit. I was impressed with them so, I tried to order the eye kit. That was unfortunately sold out, so I ended up purchasing three single eye brushes. Apparently the Sigma Makeup company re-stocks their brushes at the beginning of the month, so that would be the best time to order.
My eye brushes came in the mail quickly, in a red organza bag, along with a pamphlet with tips on how to use the brushes when applying makeup.
