Visual Fraction Measuring Cups - Concentric

A series of measuring cups, ranging from 1 cup to 1/8 cup. All sized at angles to represent their relative percentage of a whole circle - or in this case - a whole cup, for your viewing convenience. They also nicely nest together for easy storage. These ones are also concentric and can spin around if you'd rather just do that with them.
