Multiple sizes: 5 pack bottle brushes include 15 x 2.5 inch sparse top brush for beer bottles, 14.7 x 2.5 inch dense top brush for water bottles, 14.5 x 1 inch long brush for narrow neck bottles, 11.5 x 1 inch short brush for lids, and 10 x 0.2 inch cleaning brush for straws. Not easy to break: The bottle brush handles are thicker and sturdier compared to standard brushes, providing increased durability. Their ergonomic design offers a comfortable and secure grip for better control. More durable and sturdy: The bottle cleaning brushes are made with nylon bristles, which are more durable than polypropylene materials. Bristles are securely attached with thicker stainless steel wires, reducing the risk of bending. Excellent cleanliness: The 14.7 inch dense top brush features a tightly bound construction with denser bristles, making it effective for wide bottle necks and reaching the bottom of containers. Multi-purpose: The 15 inch sparse top brush works well for beer bottles, narrow-mouth bottles, and tumblers. The 14.7 inch dense top brush is ideal for water bottles, sport bottles, thermoses, jars, glasses, and mugs. The 14.5 inch long brush is suitable for narrow bottles, wine glasses, and long neck bottles. The 11.5 inch short brush is designed for cleaning lids, caps, small bottles, and spouts. The 10 inch cleaning brush is perfect for straws and small tubes.
