Slippery is a glossy base with a tinge of pink and gold pearl paired with a subtle sheen. It had some tackiness, too, but it wasn't overly thick. In order to get greater coverage out of it, one needs to use a toothpick or a tool to break up and mix all the pearls with the base, as just using it with a brush or fingertip from the surface resulted in next-to-nothing coverage (it was intended to have "sheer" coverage, per the brand).
The glossiness did cause other products to break down a bit and crease. I felt it worked better as a tacky base for increasing intensify of some of the shimmer shades, though it sometimes made it harder to blend out matte shades.
