OXO Good Grips Smart Seal

Yes, the borosilicate glass is designed to withstand thermal shock, meaning it can transition safely between extreme temperatures. However, it is best practice to let the container reach room temperature before placing it in a preheated oven to ensure longevity.

Yes, the snap-locking lids feature a silicone seal that creates a secure, leak-proof barrier. They are reliable for transporting liquids in a lunch bag or cooler without worrying about spills.

Yes, both the glass containers and the plastic lids are dishwasher safe. For the best results and to maintain the integrity of the silicone seal, we recommend placing the lids on the top rack.

Yes, all components of the OXO Good Grips Smart Seal set are BPA-free, ensuring they are safe for food storage and heating.

While the containers are designed to be stackable when filled and lidded, they do not nest perfectly like plastic bowls. They are designed to stack efficiently to maximize cabinet and refrigerator space.

This comprehensive set includes 30 pieces in total, which accounts for both the glass containers and their corresponding locking lids.
