RADIUS Source Toothbrush
Ok, I've been using this for almost a month now and what I thought was going to be awkward turns out to be comfortable. That hump in the handle........melts right into your palm. And the medium brush is more like soft, which my dentist recommended. Overall: Happy "Replaceable head toothbrush with renewable resource handle. Wood Fiber blended with PLA, a plastic derived entirely from Nebraska maize. The resulting material is 100% renewal resource." It is kind of silly that we must throw away an entire toothbrush. I'm not sure how much impact this would have, but it states something about how one prefers to live.
