Castor Oil Toothbrush Heads

Keep your routine low-waste with this 3-pack of bamboo replacement heads featuring castor-oil–based bristles (bio-nylon, vegan).

Each head has a threaded bamboo base that screws securely into our reusable aluminum handle (handle sold separately) for a snug, no-wobble fit. The plant-derived filaments deliver a smooth, gentle clean and hold their shape with everyday use. Replace heads every 4–8 weeks (or sooner if bristles splay).
