Set of 3 Pyrex Corning Nesting Bowls for mixing or for microwave and oven.  No stove top or broiler.  The large bowl is #325 (2.5L), medium #323 (1.5L) and small #322 (1L).  They have normal surface wear.  The large bowl has a hairline crack on the inner side on the bottom, but it does not go all the way through.  See photos.
