Review (5/5): These are great!
I'm all about being able to fit essentials into my wallet. I have had several occasions where I desperately need floss, and now I won't have to worry about that anymore! They each contain 12 yards, and easily fit in a credit card slot of your wallet. I was worried about the thickness, but it is just as thin as a regular credit card. It says they are "Ultra light waxed" which I would agree with, because you can't really tell that it's waxed, but it helps keep the floss from fraying.
