Anyone who uses reusable water bottles, this 2-piece cleaning brush set is absolutely essential for keeping your bottles fresh and clean! You get two different sizes - a small brush measuring 34x3.5cm (13.4x1.4 inches) perfect for standard water bottles and a larger brush at 35x9cm (13.8x3.5 inches) great for wider-mouth bottles or containers. The combination of nylon and cotton bristles is perfect - stiff enough to scrub away residue but gentle enough not to scratch your glass or plastic bottles. The wooden handles feel great in your hand and the stainless steel construction ensures durability. The hanging straps are super convenient for storage and drying between uses. Perfect for cleaning sports bottles, baby bottles, wine glasses, thermoses, or any container with narrow openings that are hard to clean properly. Dishwasher safe for easy maintenance, so cleanup is a breeze. Much better than trying to clean bottles with makeshift tools that don't reach all the surfaces. Well worth having in your kitchen for maintaining hygiene and ensuring your favorite bottles stay fresh and ready to use.
