It focuses on volume rather than length but I have to say it definitely lengthens my lashes too! It has two brushes; one for your upper lashes which is quite like the 'Falsies' brush but it's twisted, and one for your lower lashes which is small and reminds me of the Clinique lower lash mascara.
It's a really lovely mascara and at £6.99 (£8.99 after introductory offer) I think it's worth a try! It isn't clumpy at all and gives great volume :)
See you soon and stay insane!
