Stand up straight! No, this isn't your mother talking to you, this is actually a piece of advice I gave you back in January about how you can prolong the life of your nail polishes. When storing polish, it's best to keep them in a vertical position to prevent the components of the polish from separating. So when I went to rearrange my myriad of polishes, which were thrown haphazardly in a storage box in my closet, I was a little annoyed with myself. Besides the fact that many of my polishes had gone clumpy and those labeled "new" were actually quite the opposite, I began to realize that I don't think I've ever come close to finishing a bottle of nail polish. Have you?
