- Is the glass oven safe?
- Yes. The borosilicate glass is rated for oven and microwave use. Leave headroom for food to expand and avoid sudden temperature shocks such as oven to cold water.
- Are the lids leak-proof?
- OXO rates the Smart Seal lids leak-proof. The silicone gasket presses down to form the seal, so check that it sits flat before closing.
- Can these go in the freezer?
- Yes. The glass is freezer safe. Fill below the rim because liquids expand as they freeze.
- How many containers come in the set?
- Twelve pieces in total, in a rectangular shape. The listed capacity is 4 oz per container.
- Are the containers dishwasher safe?
- Yes, bases and lids are dishwasher safe. Place lids on the top rack and let gaskets dry fully before reassembling.
- How does this compare with plastic storage sets?
- Glass will not stain, hold odors or warp, and it can go in the oven. It is heavier and costs more than basic plastic, and the 4 oz size is smaller than many plastic sets.

- At Abt Electronics, for $37.99, as of our latest check.
