The brush itself is very similar to the new Benefit Roller Lash mascara and the L'Oreal Butterfly mascara, with a curved plastic applicator at the end with shorter bristles on the inside curve and longer on the outside. This helps to apply the right amount of product to the lashes and the curved shape really helps coat the whole of the lash line as well as separate the lashes. At first the formula feels quite wet and can make your lashes quite clumpy but after a week or so of drying out it thickens up and creates a clump free formula!
Unfortunately this didn't volumize my lashes as well as I thought it would. It's more of a lengthening mascara but once layered with another volumizing mascara it works really well. It doesn't smudge or transfer despite my lids sometimes getting oily and I reckon it holds up pretty well throughout the day.
