I love these! I own almost every color and use them as bases for my eyeshadows to make my shadows really stick and pop! I love how I can change the colors of my eyeshadows by using different colored Jumbo Pencils underneath-- Milk makes my colors bold and bright, Black Bean makes them sultry and smokey, etc. I also use them when doing costume makeup--Pots and Pans made an excellent silver base for my Terminator look! The only cons I have for these are that they will crease significantly if you don't use a primer underneath. Other than that, they last all day and make your eyeshadows really stand out!
A quick tip: Ulta sells a sharpener that works excellently for them.
Creamy and useful
This product is what made me fall in love with NYX's products. Very useful, as a primer, as a mixable shadow and I'm sure it has other uses as well. I also have it in black bean, which I don't use as much but apply with an angled brush along my lash line. The only complaint I have would have to be with the largeness of the stick it comes in. I didn't have a sharpener that would work with it, so I had to resort to a sharp knife and whittling, which I suppose is fine, but a little inconvenient. I've read some people melted it in the microwave and poured it into a pot, but I am not really willing to possibly ruin my appliances this way nor do I have anything suitable to put it in, so whittling was my choice. I heard you can buy a sharpener from NYX that fits it, but I digress. The product is very creamy and I found myself using it quite a bit when I needed to lighten a shadow along the brow bone. I would totally recommend it, and if you can, try and find the sharpener they sell as well. It would have saved me a lot of time if I had thought to buy one.
Decent base, but watch for creasing
I bought this as a base for lighter shadows to make them pop. I ended up with creasing. I know a lot of people swear by these, but I never can get them to work for me. They are a great bargain though, and for shorter wear times they could work well.
Cheap, Makes a great base for pigment.
Great for looks that involve what ever color, if you want it more deep or vibrant. However I did find that you need a really nice primer because since this is a creamy consistency it will set greasy on the eyelid after a while. But Milk is awesome for natural highlighting on the face and to use underneath bright colors.
