I love the look of polished nails but I hate the bottle and brush combination since the bottle can sometimes tip over by accident.  Plus I think there is a need for nail polish that was more compact and travel friendly.  Sally Hanson came out with their nail polish pen where it dries fast and you just click the top of the pen for the color to dispurse on the brush and you paint your nails.  It was very quick to apply and no worries of tipping the bottle.  Very mom friendly!
