Review (5/5): Handy floss in a plastic "card" as thin as your credit card!
These are soooo handy! Just keep them in your wallet with your credit cards and when you need floss, just pull out the length you want and tear it off at the almost-flush metal tab. My brother (a dentist for over 30 years) gave us a few of these and we're hooked. So glad we can buy them online!!
