At Maker Faire a couple of weeks ago Bob Knetzger offered me a BrushPick from a little keychain dispenser. I thought my teeth were already clean but I took one anyway because the picks looked cool, with a tiny sword on one side, a moth antenna on the other side. It turned out that my teeth were not as clean as I previously thought. I bought a 3-pack of dispensers ($(removed) on Amazon) and have been using them every day since. I need to stock up on replacement brushes to refill the containers, each of which hold 15 picks.
