Interdental Brushes 5 Pack

Pack of 5
About this product
A warm bamboo handle instead of a flimsy plastic stick. Truthbrush applied the same design logic from their toothbrushes to the most overlooked tool in the bathroom cabinet. The handles are FSC-certified Moso bamboo finished in plant-based oil, smooth and comfortable to grip.
The bristles are BPA-free nylon, the same specification used in clinical interdental brushes. Castor oil bristles are not yet commercially available at this gauge, and Truthbrush chose performance over a compromised alternative. The case contains 20 brushes across four packs of five.
Each brush can be rinsed and reused multiple times. End of life: pull the bristle head off (general waste) and compost the bamboo handle.

Why it's BRiMM
Why it's BRiMM
We think most people skip interdental care because the tools make it feel like a chore. Plastic sticks, fiddly grips, flimsy floss. These feel different. The bamboo handle is warm and smooth, finished in plant oil, and the slim design makes it easy to work through every gap without fumbling.
Dentists say interdental cleaning removes up to 40% more plaque than brushing alone. The bristles here are nylon because nothing else performs reliably at 0.4mm gauge, and Truthbrush would rather be honest about that than dress it up. They made the best version they could and they will change it the moment something better exists.
How to use
How to use
Insert gently at a slight angle. Move back and forth two or three times per gap.
Rinse after each use and allow to air dry. Do not leave submerged in water.
Each brush can be rinsed and reused multiple times before replacing.
Pairs well with Truthbrush Bamboo Toothbrush Soft Bristles for a full bamboo oral care set.
