I bought these 3 months ago because I loved the look and leak proof.  I’ve since found cracks in a few, had one of the seal flaps come off a lid while microwaving and found the seals to no longer maintain the leaks.  Very disappointed as I searched high and low to obtain the 1.5 cup size to go along with the larger 3 c size to use for work everyday.  And these were not cheap.
