Bought for my the planet, love it for the feel!
"I get it, I fell for the marketing. While plant based, the bristles ultimately are castor oil-based which ends up being nylon which also releases micro plastics. But… when you replace the head, snap off the bottom little section that connects the head to the brush. With pliers pull out the bristles at the base. Now you’d just have bamboo which you can return to the woods. I saved the best part for last. I already regularly have used an electric toothbrush. When I switched to Kaylaan ,and their toothpaste, my teeth feel like the day you leave the dentist after a cleaning. They feel amazing."
