brush heads

We have developed special brush heads made of bamboo for our KOA sonic toothbrush to save plastic. We use PLA for the inner part, which is biodegradable.

Bamboo brush heads from other manufacturers sometimes do without the PLA inner parts, which can lead to uncontrollable wobbling and short life. With the bamtoo interchangeable heads you can be sure that everything is tight and can be changed easily and without hesitation.

Dentists recommend changing the attachment every 2-3 months.


The packaging is 100% plastic-free and consists of kraft cardboard. We do our best to save plastic wherever possible.
