The whole concept of the mascara was that you only have to roll the brush over your lashes for amazing results.
Firstly I think it's decent. It's a good mascara. Lengthens, thickens and fans out my lashes. The formula is amazing and doesn't feel sticky or dry and crispy. It's a smooth formula that coats the lashes evenly from root to tip. The only think I would say is that when curling my eyelashes afterwards the product did seem to clump together which was annoying however you can avoid this by just curling your lashes before hand.
I think the packaging is super cute and classy and overall the product does wonders for my lashes! Will 100% be buying the full size when this one runs out!
