PureWick™ Flex Female External Catheters (Box of 28)
The web advertises a box of 30 of these individually wrapped external catheters for $209. My mom died after using only two of them, so I have 28 left. I believe I have the entire system somewhere too, so if you're interested in obtaining the main unit, feel free to ask me about it.
This type of catheter causes virtually no discomfort because it simply slips in a person's drawers and sits next to the aisle that will eventually require cleanup and remains there in a state of constant suction that is unlikely to bother the owner of that aisle.
