Battery-powered bubbler air pump Tube Air stone Rust prevention cover - a set of 4 items. Uses 2 D batteries, but can also operate with 1 battery. *Please note that the color and shape of the main unit and tube may differ from those in the photos. *We will try to send items with as little rust as possible, but please refrain from purchasing if you are sensitive to this, as these are used and stored by an amateur. In the event of a power outage due to an earthquake, etc., and the pump stops, what if your fish become oxygen-deprived...? Before the pump you are currently using breaks down, please secure one!! Of course, we will check the operation before shipping. (If the pump does not work upon arrival, please comment and we will exchange it.) It is also convenient to use when keeping the fish you have collected or caught alive. There may be some minor dirt, but the pump is harmless.
