For 35 years I have used a Gripit Floss Holder – http://www.gripit.biz – to floss regularly. These handy devices come with their own floss supply that can be advanced in seconds and refilled from local drug and grocery stores.
I feel good knowing I don’t clog landfills with throw away flossers. My grand kid like using Gripits too because they don’t have to put their fingers into their mouths to floss.
