I've manufactured some simple drain cleaners. I've seen something like this before, at a hardware store, so it's not something I'm going to be able to patent or

Works great. The thin profile fits much better than the bent coat hangers that I used to use.
They are made from an old, flexible vinyl cutting board.Takes about three minutes to manufacture one, using scissors.
The handle prevents it from being lost down the drain.
