Review (5/5): Just perfect
The entire thing is bamboo! I love this, because a lot of other toothbrushes try to get away with plastic bristles. I read a lot of reviews that said the bristles were too soft. This is not the case. I prefer softer bristles because harder ones can wear away the enamel. You don't need super stiff bristles! These are comparable to any soft bristles I've used before. Great packaging. Perfect toothbrush.
