A lot of nail art bloggers and Instagrammers swear by this nail oil pen, but I can't help but wonder if packaging nail oil this way is safe. The pen has a brush on one end and the oil comes out through the brush, which you can sweep across your cuticles and nails. I can see how this kind of package would be
convenient, but I would worry that the brush would pick up germs from my hands and then the germs could migrate back into the reservoir of oil and contaminate the product. Is this kind of packaging safe? Then again, a lot of nail oils come in either a nail polish bottle where you put the brush back into the bottle, or in jar packaging, so is a pen any better or worse than a bottle or jar?
