Review (5/5): Wallet-sized, strong, does the intended job nicely.  Highly recommend!
For some reason lately, I'm constantly getting food caught in my back teeth when I eat meat, certain vegetables, etc. I usually keep floss in my car and at the office, but there are times when I don't have it readily available. If I don't take care of the issue right away, my gums get really sore and swollen and painful for the next day or two.
I looked for something that would fit in my wallet. Despite a couple of reviews saying this floss was weak and would break easily, I gave it a try.
It works great. I've used it a number of times and had no issue with breaking or fraying. I ordered the 10-pack, and I put one in my wallet, a backup in my car, one in my computer bag, one in my travel bag, one in my office, and gave a few to family members.
Definitely worth the money! Highly recommend.
