Compare Food Storage Containers
Pyrex Simply Store 12-Pack Glass Food Storage Containers Set scores higher on safety - here's why.
The most important dimensions, side by side.
Soda-lime glass is chemically inert and FDA-approved — safe for daily food contact. Pyrex US uses tempered soda-lime (not borosilicate), so avoid sudden freezer-to-hot-oven transitions.
Tritan is a premium BPA-free plastic with FDA food contact approval — safer than generic polypropylene but still a plastic that contacts your food directly.
BPA-free polypropylene lids are FDA-approved and safe at normal storage temperatures — a reliable plastic choice for food-contact lids.
The lid plastic is not precisely specified beyond "BPA-free Tritan with StainShield" — a transparency gap on a surface that directly contacts your food.
Confirmed BPA-free for both the glass containers and polypropylene lids.
Confirmed BPA-free — Tritan is a copolyester that never contains BPA as an ingredient.
Pyrex has not published PFAS-free testing for the lid material — common across most brands in this category.
Rubbermaid has not published PFAS-free testing for the Brilliance line's seal components.
Oven-safe to 425°F in a preheated oven — suitable for reheating and light baking, but avoid broiling or rapid temperature changes.
Not oven-safe — Tritan plastic deforms above approximately 220°F. Containers are strictly for microwave, fridge, and freezer use.
Snap-on lids push on without locking — adequate for refrigerator storage but will not prevent leaks during transport.
The 4-latch locking clip system creates an airtight, leakproof seal — the most reliable closure mechanism in this comparison, ideal for transporting liquids.
Both glass containers and PP lids are dishwasher safe — containers on any rack, lids on the top rack.
Both containers and lids are fully dishwasher safe, with the container body going on any rack and lids on the top rack.
Simple one-handed snap lids lift on and off effortlessly — the easiest daily use in this comparison.
Four snap-lock latches require two hands and moderate force to open and close — secure but not the quickest for repeated daily fridge access.
Containers stack flat when lidded — efficient for both fridge organization and cabinet storage.
Uniform 3.2-cup containers stack perfectly and interlock — ideal for organized meal prep.
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 — 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 need shatter-proof, lightweight containers for packed lunches and daily transport
You want the most reliable leakproof seal in the category for carrying soups and liquids
You microwave food in the container regularly and want a built-in venting lid

The main thing to know
The snap-on lids are not airtight or leakproof. Pyrex Simply Store is designed for home refrigerator use — if you pack lunches or transport food, these lids will shift and leak.
Every surface that touches your food is plastic — the Tritan container body, the unspecified lid plastic, and the seal gasket. If minimizing plastic food contact is your priority, glass alternatives exist at comparable prices.
Skip this if you...
You need leakproof containers for transporting lunches, soups, or liquids
You want borosilicate glass — Pyrex US uses soda-lime glass since 1998, which has thermal shock limitations
You want PFAS-free verification on lid materials
You want to minimize plastic contact with your food — every food-contact surface here is plastic
You need oven-safe containers for fridge-to-oven cooking workflows
You care about full material transparency — the lid plastic type is not specified by Rubbermaid
