I remember seeing here on B&B a while back talk and even photos I believe of a rubber lather dish used to wipe the lather off straight razors after a few passes. They are also found in barber shops (those that still do shaving) and look like a rubber candlestick base for a thick candle. I've also only seen them in red. I've tried searching here and also an extensive Google search but come up with nothing. Can someone tell me what they are called and where I can find them?
