This is the best. I don't use the built in sponge because it gets gunky and weird really fast if you do the whole base coat, 2 coats, top coat, sparkle coat, uber thick method like me. I just press a cotton onto the sponge and it soaks up more than you need. It's acetone, so while it's drying to your skin, it removes the polish super fast.

It also comes with this "dauber" which is a wool (i think) ball on a metal stick holder thing (think the cheap easter egg dye dipper things).

It says to use on your toes, but it would get gunky real fast, so I use cotton for my toes, and use the "dauber" for clean ups that aren't too close to the nail (it's kinda big).

I love this so far !
