The first one I purchased was the Sustainable Shadow Box, I instantly fell in love with the color choices in the set as well as the amazing primer that it gave a little sample of. I admit, I picked up the set because of the beautiful outside, but it is well worth the price ($36). Link is below the picture.
The primer I mentioned above is worth buying, even if you do not buy their eyeshadow. When I do not wear the primer, my eye shadow comes off or smears really easily. Since I have been using it, my eyeshadow has been lasting the full day and looking like I just put it on. This comes in a travel size as well as the full size product, so anyone can try them for pretty cheap ($9). Links are below the picture!
