I picked up this primer from my local dollar store as it looked promising, and I'm not disappointed. For only $4, this works great!
This comes in a small pot, like the Jordana single shadows but black. The screw top pot is sort of annoying, but I can get over that because the product is so good. It's a pale pink colour, but comes off neutral on the eye and is a good matte base for any eyeshadow you want to put on top. I find it makes my eyeshadows last a lot longer on my oily lids without getting sticky/creasing.
I also use this underneath my brows to clean them up and as a matte highlight, which is really good. I will definitely be repurchasing this again, it's such a good product and only $4!
