Did you know that nearly every single plastic toothbrush made, is still out there in the world somewhere, living on as a piece of trash? So with this said can you come up with enough justifying reasons to not make the switch from your plastic toothbrush to one in bamboo? Our kids bamboo toothbrush has a handle made of 100% biodegradable, sustainably grown bamboo. The bamboo is antibacterial and a rot-resistant material so it's very well suited for this purpose. The quality bristles are made of soft, BPA-free nylon 6. The reason we use nylon 6 and not biodegradable fiber is because there is yet no biodegradable fiber that are as effective when it comes to take care of your oral health. Cinks Kids bamboo toothbrush 5-pack includes all of Cink's 5 signature colors. One color for each family member! Cink toothbrushes have been approved in accordance with the CE-standards and FDA regulations. Switch to biodegradable and spare your world of plastic.
