After a couple of weeks of testing it out, I have completely fallen in love with mascara, it is all kinds of awesome!
The wand is plastic and has a sort of scoop-shape to it which makes getting to every lash very easy. I find the wand really grips to every lash and pulls it up so you get a curled effect to your lashes. It is also very lengthening and separating which is my favourite kind of mascara. It lasts super well throughout the day and I find it really easy to remove at the end of the day with the L'Oreal Micellar Water.
Overall I am so impressed with the Roller Lash mascara as it curls, lengthens and separates my lashes really well.
I will definitely be purchasing the full size when it is released on the 1st March, and I highly recommend it to anyone who likes long, curled lashes!
