I've bitten my nails for as long as I can remember, so my cuticles are in rough shape, and my nails are short and brittle. That's why I purchased Sally Hansen's Maximum Growth Cuticle & Nail Moisture Treatment Pen. It's easy to use; all you do is pull off the cap, twist the bottom to bring out the moisturizer into the brush, and brush it onto your cuticles and bare nails. Then you massage it in and let it dry.
There's no spill and no leakage, so you don't have to worry about any messiness. It's also very portable - I keep mine in my purse to keep my cuticles moisturized on the go. Awesome product.
