Better than the boars hair bristles! I have tried other bamboo toothbrushes, but generally didn't like the long term experience of using them. However, because these brushes are replaceable and I care more about the environment than my mouth comfort, I decided to try Nathan & Son's toothbrush kit with both types of bristle heads. I will definitely be a repeat buyer of the castor oil since the boars heads taste and smell like animal. Its the real deal, but I just couldn't get past 2 tries. The best thing about both varieties is the slender shape below the bristles. This allows for a much more comfortable mouth-brushing experience versus the other bamboo brushes I have tried in the past. Hence, why I will buy again and again. Handle is great.
