I use to always have floss in my purse. While this was fine and served its purpose, using floss in a public restroom isn't ideal. Plus, trying to salvage your makeup while using standard floss is beyond my abilities. So, I would always have to make sure I had my makeup with me too. These floss sticks have been a huge improvement. They are much easier to use and don't require you to contort your face anywhere near as much as traditional floss. They also don't mess up your makeup so there is no need for me to carry it when I go out.
I also find that these floss picks are easier to use and maneuver. For getting things out of your teeth, they actually work better for me than traditional floss!
