Exquisite design: Magnetic aquarium brush with algae scraper and handle, effective and easy cleaning. Size: The small magnetic aquarium cleaner is suitable for cleaning aquarium glass with thickness less than 1/5 inch, length and width 3.7*1.8 inch. Floating: The magnetic seaweed scraper floats automatically after separation and can be picked up without getting your hands wet. Easy to move: Gently move the outer magnet to easily clean the glass inside the aquarium. Strong magnetism: The suction force generated by the strong magnet makes the two pieces close together and difficult to separate.
