This mid-century modern set of 4 glass stacking mixing bowls with snap-on lids is a practical and versatile addition to any kitchen. The clear round bowls are made of durable glass and come with matching lids, making them perfect for mixing ingredients and storing them in the refrigerator. The original design and set of components included ensure you have everything you need to start cooking up delicious meals. Bowl sizes are; 3 cup, 1 cup, 3/4 cup and 1/2 cup. I will include a orange lid that will fit a 2 cup bowl (the 2 cup bowl was chipped and I tossed it) just in case you have these and need the extra lid. These are in excellent condition.
