Zero Brush
0%
A plastic-free finger and tongue brush in one biodegradable, agar-based material.
Even bamboo brushes are not fully compostable: their bristles are nylon, they feel rough and can splinter, and the whole brush is thrown away when only the bristles wear out.
Form studies translated the mechanical action of brushing into a tactile one, each tried with ridges, bristles and wave patterns.
A finger brush with ridges and bristles.
A U-shaped piece with tiny waves turns the tongue into the brush, since the tongue reaches every corner of the teeth.
One pack for the week. No toothpaste required.
Discarded, the two pieces decompose within a month.

How it was designed
Ocean plastic, and bamboo brushes tried first-hand: nylon bristles, rough, splintering, thrown away whole.
One material for the whole brush, bristles included, that breaks down fast and needs no toothpaste.
Form studies moving brushing to the finger and the tongue, alongside a material of semolina, agar, sugarcane, mint and xylitol.
A finger brush and a tongue brush cast in resin 3D-printed moulds, in a weekly pack; they decompose within a month.
