Mara: Dental hygiene revisited: the best dental floss, Valhalla "speaker", is produced by Nordost Pharmaceuticals. It's a precious metal thin wire, meticulously delivered in mutliples and protected in an insulated transparent jacket (you have to peel it off). It's reusable!!! Recommended by the Boolagonian dental association!!!
BTW, the good thing about the Lyra toothpick is, it too is RE-USABLE. You zap it in the microwave & it's sterilised. Damnation of a deal! (can't say "hell" can I)
