Absolutely fantastic flossers. These are the perfect answer if you are looking for something that is completely biodegradable. I tend to pick and floss my teeth as I'm watching tv, and for a while (whilst previously using the plastic ones) I noticed little bits in my mouth which I assumed were bits of food which I then swallowed. At some point I decided to pick the bits out before swallowing and was horrified to see that they were in fact tiny bits of white plastic from the end of the pick! The plastic ones are so tapered and flimsy that the ends break off between your teeth. These brilliant picks from Wearth are made from corn starch and bamboo and the ends do not break off in your mouth. I am a complete convert and would recommend them to anyone who wants to reduce their consumption of plastic....literally!
