Anchor Hocking glass food storage containers are essential in any kitchen. These products feature durable glass bottoms under sturdy plastic lids. The two pieces join together smoothly and tightly, so you can carry soups, salads and even whole meals to work worry-free. Save yourself time cleaning by hand, as the dishwasher will handle the mess. Reuse again and again, as, unlike plastic, the glass won't deform or discolor. When you're finished, save yourself room in cabinets with the stackable nesting feature. Tempered-Tough Glass is built-to last. It is microwave, pre-heated oven, freezer and dishwasher-safe.
