With this Water Pot, I’ve no worries whatsoever. Sure, it might be a tad expensive, but the design really does work. It’s about 3/4ths the size of a coffee mug so it’s large enough to clean brushes. I just place a piece of cardboard or notepad on top to prevent evaporation and have no fears that it would tip over if bumped.
