NEW PRODUCT

Castor Oil Toothbrush Kit

Sale price$19.99

A low-waste, vegan alternative to heavy micro-plastic shedding toothbrushes. This kit includes three bamboo replacement heads with castor-oil–based bristles (bio-based) and a reusable aluminum handle. Each bamboo head screws securely into the handle for quick changes and a sturdy, no-wobble feel. The castor-derived bristles deliver a smooth, consistent clean with modern durability that's great for everyday brushing..

Bristle firmness level: Soft-Medium (gentle daily clean)

Why you’ll like it

  • Low-waste by design: Keep the aluminum handle for years; replace only the head.
  • Plant-derived bristles (vegan): Bio-based nylon made from castor oil seeds—lower fossil-plastic content than conventional nylon, with resilient, smooth tips.
  • Solid, no-wobble fit: Threaded bamboo base screws into the handle for a snug, stable brush head.
  • Minimal + timeless: Warm bamboo + aluminum = a bathroom kit that looks as good as it works.
