Compare Food Storage Containers
Rubbermaid Brilliance Glass Food Storage Containers (3.2 Cup, Set of 4) scores higher on safety - here's why.
The most important dimensions, side by side.
Soda-lime glass is chemically inert and FDA-approved β safe for daily food contact. Pyrex US uses tempered soda-lime (not borosilicate), so avoid sudden freezer-to-hot-oven transitions.
Tempered soda-lime glass is chemically inert and FDA-approved for food contact. It will not leach chemicals into your food at any storage temperature. Avoid extreme temperature swings like freezer-to-hot-oven to prevent thermal shock cracking.
BPA-free polypropylene lids are FDA-approved and safe at normal storage temperatures β a reliable plastic choice for food-contact lids.
Rubbermaid calls the lid material 'StainShield' but does not disclose the specific plastic type. While it is marketed as BPA-free, the lack of transparency on lid composition is a concern since the lid directly contacts your food.
Confirmed BPA-free for both the glass containers and polypropylene lids.
Both the glass containers and StainShield lids are confirmed BPA-free by Rubbermaid.
Pyrex has not published PFAS-free testing for the lid material β common across most brands in this category.
Rubbermaid has not published any PFAS-free testing for the Brilliance Glass lid seal. This is common across most food storage brands in this category.
Oven-safe to 425Β°F in a preheated oven β suitable for reheating and light baking, but avoid broiling or rapid temperature changes.
Oven-safe to 450Β°F without the lid β suitable for reheating, baking, and light roasting directly from the refrigerator.
Snap-on lids push on without locking β adequate for refrigerator storage but will not prevent leaks during transport.
The snap-seal lids provide airtight, leak-proof closure that handles soups and sauces reliably. A solid choice for packed lunches and meal prep transport.
Both glass containers and PP lids are dishwasher safe β containers on any rack, lids on the top rack.
Glass containers and lids are both dishwasher safe. Place lids on the top rack for best longevity.
Simple one-handed snap lids lift on and off effortlessly β the easiest daily use in this comparison.
The lids snap shut with latches on two sides, requiring both hands to fully seal. Slightly less convenient for quick fridge grabs, but the payoff is a reliably airtight closure.
Containers stack flat when lidded β efficient for both fridge organization and cabinet storage.
Rectangular containers with flat lids stack neatly in the fridge and cabinet, making efficient use of shelf space.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You primarily store leftovers in the refrigerator and want a safe glass alternative to plastic
You want the simplest possible daily use β one-handed snap lids open and close effortlessly
You need an affordable 12-container glass set for under $28
You trust the Pyrex heritage brand and want easy replacement lid availability
You want glass containers with leak-proof lids that can go from freezer to oven to dishwasher
You already trust the Rubbermaid Brilliance brand and want the glass upgrade from the plastic version
You pack lunches or transport food and need reliable snap-seal leak protection
You want oven-safe containers rated to 450 degrees F for reheating and light baking
The main thing to know
The snap-on lids are not airtight or leakproof. Pyrex Simply Store is designed for home refrigerator use β if you pack lunches or transport food, these lids will shift and leak.
The lid material is Rubbermaid's proprietary 'StainShield' plastic with no disclosed resin type. While it is BPA-free, the lack of material transparency is why this glass container scores lower than you might expect.
Skip this if you...
You need leakproof containers for transporting lunches, soups, or liquids
You want borosilicate glass β Pyrex US uses soda-lime glass since 1998, which has thermal shock limitations
You want PFAS-free verification on lid materials
You want full material transparency on every food-contact surface including the lid
You prefer borosilicate glass for better thermal shock resistance when moving between extreme temperatures
You want the most affordable glass storage option and are fine with press-fit lids
