These measuring cups work best in a pinch. When you pinch the sides, that is, to reveal a convenient pour spout. This set of measuring cups are space savers, too; the heat and stain-resistant silicone cups expand for use and collapse for convenient storage.
The four piece measuring cup set includes a 1, 1/2, 1/3, and 1/4 cup measurer along with a storage ring. Top-rack dishwasher safe. Not for use in microwave.
