From the forest,
to your hand
To keep forests healthy, trees must be carefully thinned—
creating space for light and growth. From this process comes
thinned timber, reborn as a product made for the human hand.
The warmth of wood, with lasting comfort and cleanliness.
A new expression of nature—without compromising beauty or
usability.

Using thinned wood
nurtures the forest.
When too many trees crowd a forest, nutrients can no longer reach them all, so trees grow thin and weak — and their ability to absorb CO2 fades.
But with careful thinning — removing some trees to make room - sunlight fills the forest, and the remaining trees grow freely and strong.
As trees grow thick and full of life, the entire forest becomes healthier and absorbs much more CO2.
Using toothbrushes made from CXP — a material made from thinned wood — supports the cycle that keeps forests healthy.
