I like Sally Hansen's Color Quick Fast Dry Nail Color Pen. This nail pen really makes painting my nails more convenient and made less of a mess. I love how you have the control of how much nail polish is emitted off of the nail pen. These nail pens create a smooth mess free nail and I love how shiny the nail polish is. I am also prone to shaky hands when I paint my nails but by using the nail pen by Sally Hansen I do not have to worry about getting nail polish all over my fingers. I also love how many various nail polish colors are offered in these nail pens by Sally Hansen. I have lots of friends like me who tend to make a mess on their hands when they paint their nails so I am sure there are plenty of other women who struggle from the same problem and could really benefit from buying these nail polish pens by Sally Hansen. This is a great product and it really does make painting your nails easier and quicker.
