OXO LockTop containers were designed with leakproof, airtight lids that snap on easily and confidently. Just push the outer frame down onto the lid to engage the inner locking tabs and the silicone ring for an instant, spill-proof seal. Durable, BPA-free Tritan container bodies resist warping and staining, and are crystal clear to reveal contents inside. Lids are also clear to make contents viewable from above. Lock Top containers go safely from the freezer, to the microwave, to the dishwasher. LockTop bodies nest inside each other for convenient storage and each lid fits multiple ontainer sizes. Containers stack neatly without toppling, to optimize space in the refrigerator or freezer. 7" x 5.25" x 2.25" high.
