I received the EB 13 brush in my ipsy bag a few months ago and FELL in love. So then I bought the seven set, because it was on sale and I had a promo code, and it still had that same amazing quality but I wasn't able to use all the brushes because some of them were for foundation (which I don't wear every day) but I found ways now to integrate them into my daily routine. The brush in my ipsy bag wowed me so much that I was willing to pay the full price for these brushes because they blend so well, they clean very well (which is very important to me), and they aren't specific for one thing. You can use the brushes for many things in your beauty routine. The EB 13, for example, could be used as a crease brush or to blend out your concealer- those are the two ways I've used it- and I'm sure that it could be used in many other ways.
If you have the chance to purchase these do it!
