I don't know what magic is in these that it's just as smudge resistant as my most waterproof mascara AND actually possible to wash off (unlike said waterproof mascara) but I love them!! The colors are great and go on strong.
One thing to note is the mascara wand is very thick and it makes it somewhat difficult to apply to the corners of the eyes- not something worth taking off a star over, but something to just keep in mind while purchasing.
(I'm wearing the blue and green in the pictures!)
I love that it does last quite a long time. I basically wore it for 15 hours and I loved how vibrant it lasted!
They're very pigmented, I love the color, and it's thin without coming off easily!
