The Pawfly Aquarium Strong Magnetic Brush is a powerful and easy-to-use tool for cleaning your fish tank. Made of high-quality materials, it is durable and will last you for years. The strong magnet holds the brush tightly to the glass surface, making it easier to move around and clean difficult areas. The detachable blade is made of stainless steel and plastic, and can be used to scrape hard stains or minerals from the glass surface. The handle has a round slot on it for better grip, and the brush is easy to store and float if detached.
