2pcs Tube Cleaning Brush for Hair Brush Cleaner Aquarium Brush Fish Tank Brush Aquarium Cleaning Tool Fish Tank Cleaning Brush aquatainer Piping Bottle Brush Spring

I feel like I’m constantly cleaning my fish aquarium, which is a constant struggle to find brushes that fit into odd shapes and tiny spaces.I got these, expecting them to be all bendy and helpful. They are, somewhat.The brush tips are very fluffy and can clean a bigger diameter. The brush ‘handle’ is very springy and flexible, but the tip where the brush is isn’t flexible at all. It’s not even very bendable. So it can’t go down a tube and around a corner.I’ll use them and maybe they’ll find other purposes, like cleaning the bathroom drain?
