🛍️ Sustainable Tomorrow Zen Brush – A durable sonic toothbrush with bamboo heads and a wood-grain handle.

🌿 Material: Brush heads carved from FSC-certified bamboo, 95% raw bamboo with a small cornstarch core.

🚫 Petroleum-Plastic-Free Bristles: Soft bristles made from castor bean oil. This is Nylon 1010, a fully plant-based polymer, not petroleum nylon. Packaging is 100% plastic-free.

🧼 Use: 5 cleaning modes (including Sensitive and White), up to 38,000 vibrations per minute and a 30-day battery life.

⚠️ Plastic Parts, Honestly: The handle looks like bamboo but is recyclable ABS plastic, used to keep the electronics waterproof. The maker states this plainly. If you want zero plastic, choose a manual bamboo brush instead.

♻️ End Of Life: The bamboo head breaks down in about six months in a home compost. The castor oil bristles are plant-based but still a polymer, so they break down far more slowly than the bamboo does.
