Compare Food Storage Containers
Glasslock Premium 8-Cup/63oz Glass Food Storage Containers (2-Pack) scores higher on safety - here's why.
The most important dimensions, side by side.
Borosilicate glass is the gold standard for food-contact safety — chemically inert, handles extreme temperature changes, and zero chemical migration into your food.
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.
Food-grade polypropylene lids are FDA-approved and BPA-free by nature — one of the safest and most well-characterized plastics for food contact.
BPA-free polypropylene lids are FDA-approved and safe at normal storage temperatures — a reliable plastic choice for food-contact lids.
Confirmed BPA-free for both the borosilicate glass container and polypropylene lid.
Confirmed BPA-free for both the glass containers and polypropylene lids.
No PFAS-free testing has been published for the lid seal — common across the entire category. The silicone gasket is not a PFAS risk by material nature.
Pyrex has not published PFAS-free testing for the lid material — common across most brands in this category.
Rated to 500°F — the highest oven temperature in this category. Handles freezer-to-oven transitions, roasting, and baking with ease.
Oven-safe to 425°F in a preheated oven — suitable for reheating and light baking, but avoid broiling or rapid temperature changes.
Four-sided locking clips with silicone seal create a fully leakproof, airtight closure — safe for soups, sauces, and liquid transport.
Snap-on lids push on without locking — adequate for refrigerator storage but will not prevent leaks during transport.
Both glass container and lid are fully dishwasher safe.
Both glass containers and PP lids are dishwasher safe — containers on any rack, lids on the top rack.
Four locking tabs require two hands to open and close — slightly frustrating for quick access but necessary for the leakproof seal.
Simple one-handed snap lids lift on and off effortlessly — the easiest daily use in this comparison.
Rectangular containers stack neatly when lidded — efficient for fridge and pantry organization.
Containers stack flat when lidded — efficient for both fridge organization and cabinet storage.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want the safest material combination available — borosilicate glass with disclosed food-grade PP lids
You need leakproof containers for transporting soups, sauces, or meal prep
You want the highest oven temperature rating in this category at 500°F
You prefer large 8-cup containers for batch cooking and family meal prep
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
The main thing to know
At $15 per container, this is 5x more expensive per piece than the Pyrex Simply Store 12-pack. The premium is justified for families who prioritize material safety and transport, but budget-conscious buyers can get safe glass storage for much less.
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.
Skip this if you...
You are on a budget — at $15/piece, a full set of containers adds up quickly
You prefer one-handed convenience — the 4-tab locking mechanism requires two hands
You want a variety of container sizes — this set only includes 8-cup containers
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
Neither of these quite what you're looking for?
