This set of six dry-measure cups nests neatly just like traditional Russian matryoshkas. They accurately measure 1/4, 1/3, 1/2, 2/3, 3/4 and 1 full cup, and they're built from heavy-duty, food-safe, long-life engineered plastics. M-Cups are useful, easy to store, and quite charming... so why not doll up YOUR kitchen with a little Russian folklore
