    The bottom line

    What the product listing won't tell you

    Know before you buy

    OXO does not disclose the specific plastic type used in the lid. While it is BPA-free with a silicone gasket, buyers who want full material transparency should consider alternatives like Glasslock that disclose PP lids.

    Buy it if

    • You need a leakproof container for transporting soups, sauces, or packed lunches

  1. You want borosilicate glass that can go from freezer to oven without thawing

  2. You prioritize seal performance and are comfortable with OXO's BPA-free claim without specific polymer disclosure

  3. You want a container that stacks neatly in the fridge and nests in the cabinet

    4. Skip if

    • You want full material transparency on lid composition — OXO does not disclose the specific plastic type

    • You prefer one-handed convenience — the 4-tab locking mechanism requires two hands

    • You need a budget-friendly set — at $14.99 per single container, a full set adds up quickly

    R3 Verdict

    The borosilicate glass body is the gold standard for food safety — chemically inert and thermally shock-resistant. However, OXO does not disclose the specific plastic used in the lid, which limits the safety score despite the silicone gasket.

    Criteria

    Container Body Material
    10/10

    Borosilicate glass is the gold standard for food-contact safety — chemically inert, handles freezer-to-oven transitions without shattering, and zero chemical migration.

    Lid Material
    2/10

    OXO does not disclose the specific plastic type used in the lid. While it includes a silicone gasket and is BPA-free, the lack of material transparency is a concern since the lid contacts your food directly.

    BPA-Free
    Functional PerformanceImportant

    R3 Verdict

    Perfect functional performance. The borosilicate glass handles oven temperatures safely, and the 4-tab locking clip system with silicone gasket creates a genuinely leakproof seal — the best in this category for transport.

    Criteria

    Oven-Safe Maximum Temperature
    10/10

    Borosilicate glass goes from freezer to preheated oven without needing to thaw first — full versatility for reheating, baking, and roasting.

    Daily UsabilityNice to have

    R3 Verdict

    Dishwasher safe and stackable, but the 4-tab locking mechanism requires two hands to open and close — a minor daily friction point compared to simpler snap-on designs.

    Criteria

    Dishwasher Safe
    10/10

    Both glass container and lid are fully dishwasher safe.

    #16 of 16 food storage containers reviewed

    10/10

    Confirmed BPA-free for both the borosilicate glass container and plastic lid components.

    PFAS-Free Lid Seal
    5/10

    OXO has not published PFAS-free testing for the silicone gasket or lid — common across most brands in this category.

    Seal Type
    10/10

    Four locking tabs with a silicone gasket create a fully leakproof, airtight seal — safe for soups, sauces, and anything you need to transport.

    Lid Mechanism Ease
    6/10

    Four locking tabs require two hands to open and close — slightly frustrating for quick refrigerator access but the trade-off for a leakproof seal.

    Stackable Design
    10/10

    Stacks neatly in the fridge or freezer and nests in the cabinet when stored without lids.
