One of my favorite, unique online stores: www.perpetualkid.com
How cute is this!! Not only is a unique kitchen accessory, it serves as measuring cups!! Here's the description:
This set of 6 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 engineering plastics.
