This morning, it has come to our attention that if you think you're being clever/saving money by hoarding the nail strips you didn't use up the first time around, you're actually not accomplishing either of those goals. Once opened and left to sit (even in an airtight container, ugh), they will no longer work. The sticky is gone. We repeat, the sticky is gone! Benefit from our (massive, as evidenced by the photo) mistake and make this one smart move the next time you...erm, strip: Bring a friend! Share your next box with a pal. Apply them together. Have a cocktail while you're at it if you wanna. Just don't save them! Save yourselves!
