Clean bottles, cleaner oceans. The Full Circle Clean Ocean Bottle Brush is made 100% from recycled ghost fishing nets recovered from the sea — one of the most damaging forms of ocean plastic waste — and built to deep clean water bottles, baby bottles, flasks, and tumblers. The narrow head fits into small-neck bottles and glassware where standard brushes can't reach. Tough, durable bristles scrub thoroughly without scratching. The ergonomic handle protects your wrist and reduces the muscle effort required for deep cleaning. Top-rack dishwasher safe to keep the brush itself clean between uses.
