- Are these containers really leakproof?
- Yes, when all four tabs are locked. The silicone gasket compresses against the glass rim, so soups and sauces stay in even when the container is tipped in a bag.
- Can they go from the freezer straight to the oven?
- The borosilicate glass is made for freezer, oven and microwave use. Let frozen glass warm slightly before oven heat to avoid thermal shock, and never use the lid in the oven.
- Are the lids and gasket dishwasher safe?
- Yes. Put the glass, lid and gasket on the top rack. Remove the gasket first so food debris does not get trapped under it.
- Do the sizes nest together?
- The 13 oz, 28 oz and 64 oz containers nest when empty, and the lids stack. Check that the lid matches its container size, since lids are not interchangeable across sizes.
- How do they compare with clip-lid glass containers?
- The four-tab lid seals more firmly than most two-clip lids, which owners say leak more. The trade-off is stiffer closing and bulkier lids.
- Is the glass safe for kids to carry?
- The glass is sturdy but heavy, so it suits older children and adults better. For young kids, a plastic or stainless container is lighter and less breakable.
