To have a nail brush that represents Conscious Living is a challenge. The bristles must not be animal or plastic. The usual alternative is tampico from the agave cactus, but it bends too much and doesn't last. But this brush from Wild & Stone has the answer - sisal, as used in rope, from the sisal palm. It's solid and does the job. Lightly laquered wood means you can feel the wood, but it can withstand the water. A truly excellent product, and the only one in the world. And full marks to Wild & Stone for using only cardboard packaging, unlike my other suppliers who stubbornly use plastic despite my insisting they don't.
