As per NYX
Maximize the intensity, longevity and unashamed brilliance of your eye shadow statements with our eye shadow primer pots. Each of the three NYX Eye Shadow Bases—for vibrant, pearl or neutral tones—creates a smooth canvas for color, increases its durability and prevents fallout.
NYX Eye Shadow Base is one of the good drugstore/ affordable eyeshadow base. Its creamy in texture so application is pretty easy. Stays on for good 8 hours without creasing. You need just the tiny-est bit of the product to cover the entire eye so this one pot will last forever. It gives a matte canvas so that all the eye shadows irrespective of their type can show their true self (by type I mean glitter/shimmer/matte/metallic etc)
I didn’t find any downside of this product except few users can find pot packaging unhygienic.
If you want an affordable inexpensive eyeshadow base go for NYX Eye Shadow Base.
