This is a used item, only used a few times! Get sparkling clean glass without getting your hands wet! This magnetic cleaner makes cleaning fun. Strong magnets effectively remove algae! Easy-to-hold shape makes it user-friendly. Easily clean aquariums, high windows, and other hard-to-reach places!! I used it to clean the glass of a heavy aquarium, but I don't have it anymore. It's a very convenient item because you can clean from the outside without changing the water.
