Pyrex vs Anchor Hocking: two American glass names, one thin spec sheet
Both are tempered glass with a snap-on lid. Pyrex publishes set contents, dimensions and a 2-year warranty. Anchor publishes 'oven, microwave, dishwasher, refrigerator and freezer safe' and 'made in the USA' — and little else. Here is what the pages say.

The verdict
What each page publishes
We score from the maker's page, and here the pages differ more than the products. Pyrex's Simply Store page lists every piece in the set with dimensions (a 3-cup rectangle is 7.5 by 5.5 by 1.75 inches; a 7-cup round is 7.25 inches across), states the lids are top-rack dishwasher, freezer and microwave safe, says the glass resists stains and odors, and prints a 2-year limited warranty on glass and lids. It makes no oven statement for this set.
Anchor Hocking's TrueSeal page says the containers are BPA-free, "oven, microwave, dishwasher, refrigerator & freezer safe", "designed to prevent spills & leaks", stackable, with clear lid windows, and made in the USA. It publishes no oven temperature, no set contents, no dimensions and no warranty on that page. That isn't a mark against the glass; it's a mark against the spec sheet, and the rubric's lid-longevity score reflects it.
Two snap-on lids
Pyrex describes its lid as airtight. Anchor describes its lid as designed to prevent spills and leaks. Neither is the word "leak-proof", and neither lid has latches or a described gasket. Both seal a container that stays upright: fridge, counter, a lunch bag carried flat. For the other case — the backpack, the gym bag — the Snapware set on this page uses Pyrex's glass under a four-tab lid the maker calls airtight and leak-proof, with a lifetime lid warranty. That set is the practical winner of a Pyrex-versus-Anchor search for anyone whose lunch travels.
The oven question comes up with both brands. Pyrex's bakeware rules are not the Simply Store set's rules; Anchor says oven-safe without a number. The safe reading for both is the one Snapware prints: preheated oven, glass only, no sudden temperature changes. Every glass set's oven wording is tabled on the glass roundup.

What the spec page supports
- Nine sizes cover a week of lunches plus leftovers, and the rounds nest
- Tempered glass that shrugs off tomato stains and curry odors
- The 2-year warranty covers the lids, which is where every glass set dies first
Where it falls short
- Press-on lids: fine upright in a bag, not something to trust on its side with soup
- No oven rating is stated on this set's page — treat it as fridge, freezer and microwave gear
- Mixed sizes mean the rectangles and rounds don't stack as one tower
Skip this if…
…your meals ride sideways in a backpack — a latched, gasketed lid (Glasslock, Rubbermaid Brilliance) is the right buy, not a press-on lid.

Skip this if…
…you want a lid the maker calls leak-proof — Anchor says 'prevent spills & leaks', which is a softer claim than Snapware's.

How Meal & Macro scores gear
Units we claim to have tested: 0
Plenty of sites say they packed every container on the list for a week. We didn't, and we say so. What we do instead: read the lid, material and care ratings the maker actually publishes and repeat its wording ("leak-proof", "oven safe to 450°F", "top-rack only"), do the container-fit and ice-pack arithmetic from published dimensions and the USDA's numbers, and score every pick on a public rubric for its category that weights the seal, the material and the fit first. Every figure links to where it came from; where the maker's page would not load we cite a retailer and say so.
Scores are editorial judgments from that documented research, not test results. Commissions never set a score or decide a pick. The rubrics and their weights are published.
Questions
Frequently asked
Is Anchor Hocking made in the USA?
The TrueSeal page says "Made in the USA". Pyrex's Simply Store page doesn't state an origin.
Are Anchor Hocking TrueSeal lids leak-proof?
The page says "designed to prevent spills & leaks", which is not a leak-proof claim. Carry it upright.
Can Pyrex Simply Store go in the oven?
The set's page doesn't say so; it rates the glass for microwave, freezer and dishwasher. Snapware's Pyrex-glass set states preheated-oven use for the glass.
