Mighty Mug Barware : Double Old Fashioned (Stemless) - Set of 2

These work great. Haven't needed to clean a spill, which makes me popular again at home.

Perfect!

Just what my low vision husband needed. Stays put if he brushes against it and lifts up easily for a drink. Wish we had known about it sooner.
