Wet formula, has a straight, rubber wand. The bristles on it has two long sides, and two short sides, so it gives you a variety. This lengthens my BOTTOM lashes very well and it darkens them (but not too dramatic). On my top lashes it does a "so-so" kind of job, and theres probably better ones out there. If you do get this mascara in your eye, it kinda burns...bad. But it does live up to its expectations which is Lengthening.
The long bristles on the rubber wand really gets into your lashes and lengthens them, and the short bristles, help kind of "thicken up" the lash look so to say (but once again NOT DRAMATIC).
But it does look amazing for lower bottom lashes.
