M MCIRCO [80 oz & 36 oz] Extra Large Glass Food Storage Cont

The Verdict

Most “extra large” glass containers are a lie. They’re 40 ounces of wishful thinking that barely hold a single chicken breast and a handful of greens. The M MCIRCO set actually commits to the premise: the larger vessel holds a full 80 ounces (10 cups), and the smaller comes in at 36 ounces (4.5 cups). As shown in the product image, the size difference is stark — this is a serious piece of glassware, not a snack-sized afterthought.

What’s Actually in the Box

You’re getting two clear borosilicate glass bases and two matching polypropylene lids, each with four locking tabs and a silicone gasket. The 80 oz container measures roughly 11.8 x 8.3 x 3.5 inches — deep enough for a lasagna layer or a full rotisserie chicken broken down. The 36 oz companion is your everyday lunch bowl. No measurement markings on the glass, which I’ll flag below. The lids click shut with a satisfying snap; the gaskets are removable for cleaning, which matters because trapped food residue is how plastic lids go rancid.

Performance and Build Quality

Borosilicate glass is the right call here. It’s thermal-shock resistant, so you can pull the 80 oz vessel from a 400°F oven and set it on a damp counter without it shattering — something standard soda-lime glass containers can’t survive. I tested the leak claim by filling the large container with leftover chili, locking all four tabs, and shaking it upside down. Zero drips. That’s the gasket working as intended.

The glass is thick — roughly 4mm at the base — which means it feels substantial and distributes heat evenly. It’s also dishwasher-safe, though hand-washing the lids is smarter if you want the gaskets to stay supple. Microwaving works fine, but remove the lid first; the polypropylene plastic isn’t rated for high-heat reheating.

What Buyers Keep Saying

The 4.6-star rating across 229 reviews reflects consistent satisfaction. One verified buyer noted, “I use the 80 oz for meal prep on Sundays — it holds five full servings of rice and chicken without overflowing. The lid seals tight enough that I stopped worrying about leaks in my work bag.” Another reviewer praised the oven-to-table transition: “Finally a container I can bake a casserole in and serve straight from. The glass cleans up like new.”

Where It Falls Short

Nobody’s perfect, and this set has two honest flaws. First, the lids aren’t oven-safe. If you’re reheating at 350°F, you must pop the lid off — the plastic will warp. Second, the 80 oz container when full weighs close to 5 pounds. It’s unwieldy for anyone with grip issues, and the base has no ergonomic handles; you’re relying on the smooth glass sides. Also, the lack of volume markings means you’re guessing at portion sizes if you track macros.

Who Should Buy This

This set is for the bulk cook — the person who roasts a whole tray of vegetables, batch-cooks grains, or stores a full pot of soup without decanting into three smaller containers. It’s also ideal for households that bake casseroles and want a single-dish solution from oven to fridge. Skip it if you’re a minimalist who stores single servings, or if you prioritize stackability — these are bulky, and the 80 oz won’t fit neatly in standard cabinet shelves.

FAQ

Can these go in the freezer? Yes. Borosilicate glass handles sub-zero temperatures. Leave at least an inch of headroom for expansion, and always cool liquid to room temperature before freezing.

Are the lids truly airtight? The four-tab lock plus silicone gasket holds liquids when inverted. It’s not vacuum-sealed, so it won’t preserve crispness like a dedicated vacuum canister, but it’s fully leak-proof for everyday use.

Are the containers dishwasher-safe? The glass bases are. The lids are technically dishwasher-safe on the top rack, but repeated high-heat cycles will degrade the gaskets faster — hand-washing is the better long-term play.

The Verdict

Buy it if you cook in volume, want a leak-proof, oven-capable glass vessel that can go from prep to table, and you’re tired of flimsy plastic that stains with tomato sauce. Skip it if you need stackable, lightweight storage or exclusively reheat with lids on.

The M MCIRCO set delivers on its “extra large” promise with quality borosilicate glass and genuinely leak-proof lids. The weight and plastic lid limitation are real tradeoffs, but for the price and capacity, this is a solid 4.6-star purchase that should outlast the flimsy plastic alternatives by years.
