4-in-1 Bottle Gap Cleaner Brush

Four brushes in one tool. The 4-in-1 Bottle Gap Cleaner Brush tackles every hard-to-reach spot on your water bottles, tumblers, and travel mugs — the lid grooves, the threaded gap, the corners, and deep inside the body. U-shaped silicone brush lifts stubborn stains around the rim without scratching. Twisted-wire gap brush slips into the narrow groove on the lid. Corner bristle brush digs dirt out of tight interior corners. Deep interior brush reaches the bottom of tall bottles. Double-sided silicone wraps the cup wall — soft, won't scratch. Hanging loop for drip-dry storage; takes up almost no space. Material: Plastic + silicone · Weight: 139g · Size: 28–33 × 6.5cm
