If you like getting your cooking and baking measurements correct, then M-Cups Measuring Cups should be nested in your kitchen. Inspired by Russian matryoshka nesting dolls, the measuring cups fit neatly into each other, to save counter space, and to help make cooking a little more adorable.
Three dolls turn into six measuring cups, 1/4, 1/3, 1/2, 2/3, 3/4 and 1 full cup. Sorry, metric system.
