Born Pretty Store have a range of cuticle oil pens in various scents, almond, lavender, coconut, peach and this one which is pineapple oil.
It comes packaged in a cardboard box, and the pen itself is silver. To use this pen you have to twist the end in order to make the oil come down in to the pen bristles. The first time it takes a lot of twisting to make it happen.
I've brushed the cuticle oil around my cuticles in the below picture, I also use it under the length of my nail. This one is scented of pineapple, sinks in to the skin quickly and the scent doesn't last.
I use a cuticle oil at least once a day, it helps to increase the circulation around your nails, which helps your nails to grow. I think it also helps the cuticle area look a lot more visually appealing.
