Razab 80oz Borosilicate Glass Storage Containers Review: 6-Month Test Results

Are you tired of plastic containers that stain, warp, and hold onto last week’s garlic smell? I was too, which is why I switched to glass food storage containers for my meal prep routine.

The Razab 80oz Borosilicate Glass Storage Containers have been my daily go-to for six months of rigorous meal prep. With a massive 10-cup capacity and heat resistance up to 800°F, these containers promise restaurant-grade durability for home kitchens. They’re designed for the freezer-to-oven lifestyle that serious meal preppers demand.

After using these glass meal prep containers every single day for half a year, I’m ready to share what works, what could be improved, and whether they deserve a spot in your kitchen. The short answer: they’ve earned their place, with a few caveats about the lids.

What I Liked

Premium Borosilicate Glass Construction

The Razab containers use borosilicate glass, the same material found in laboratory glassware and high-end cookware. This isn’t your standard tempered glass that might crack under thermal stress. The borosilicate construction handles temperature swings from freezer to oven without breaking a sweat.

I’ve moved these containers directly from a cold refrigerator to a preheated oven multiple times with zero issues. The glass feels substantial and sturdy without being unnecessarily heavy for its size.

Generous 80oz Capacity for Meal Prep

At 80 ounces or 10 cups, these containers hold serious volume. A single container fits enough ground beef, rice, or stew for an entire week of lunches. For fitness enthusiasts who meal prep in bulk, this capacity is ideal.

The rectangular shape maximizes refrigerator space compared to round containers. Less dead space means more efficient storage and easier stacking.

Oven, Freezer, Microwave, and Dishwasher Safe

The versatility here is excellent. These glass containers work in the oven up to 500°F, survive freezer temperatures without cracking, and reheat safely in the microwave. The glass base is also dishwasher safe, making cleanup straightforward.

For batch cooking, I can bake directly in the container, let it cool, snap on the lid, and store it immediately. This eliminates transferring food between baking dishes and storage containers.

Secure Airtight Locking System

The lid features flaps on all four sides that snap onto the container rim. This creates a secure, airtight seal that I’ve tested with soups and sauces without any leaks. The BPA-free silicone gasket ensures food stays fresh longer than typical snap-lid containers.

Each locking flap clicks into place with satisfying confirmation. Unlike some competing designs, you can feel when the seal is properly engaged.

Minimal Wear After Daily Use

After six months of daily use for meal prep, these containers show minimal wear on the glass itself. No staining from tomato sauce, no lingering odors from spicy foods, and no cloudiness from repeated dishwasher cycles. The glass maintains its crystal-clear appearance.

The nonporous surface means food residue washes away completely. I’ve stored everything from overnight oats to curry chicken without any permanent marks.

What Needs Improvement

Plastic Lid Longevity Concerns

The one area where I have reservations is the plastic lid construction. While the locking mechanism works well, the plastic itself is thinner than I’d prefer. After six months, everything still functions properly, but I can see this component potentially failing before the glass does.

The silicone seal holds up fine, but the plastic housing could be more robust. This seems to be an industry-wide issue with glass containers that pair premium glass with standard plastic lids.

Heavy Glass Weight

At 6.69 pounds for the set, these aren’t containers you’ll casually toss in a lunch bag. The substantial glass construction that provides durability also means these are best suited for home use rather than daily transport.

If you’re looking for containers to bring to work every day, lighter options exist. These excel in the kitchen but aren’t ideal for commuters.

Lids Not Microwave Safe

While the glass base handles the microwave without issues, you must remove the lid before reheating. The plastic lid is not microwave safe and can warp or release chemicals if heated. Some competitors offer vented lids that allow microwave use with the lid on.

This isn’t a major inconvenience, but it’s worth noting if quick reheating without extra steps matters to your workflow.

How It Compares

The glass food storage container market has several established players. Here’s how Razab stacks up against the competition.

OXO Good Grips Smart Seal is often cited as the expert testing winner. OXO’s containers feature superior lid engineering with a thick, removable silicone gasket that’s easy to clean. The lids require minimal effort to open and close. However, OXO commands a premium price that’s notably higher than Razab’s offering.

Pyrex Snapware brings decades of brand trust and a four-latch system similar to Razab’s design. Pyrex containers passed leak and airtight tests in expert reviews, though users report the lids require more force to seal and unseal. Pyrex offers longer warranty coverage with two years for glass and lifetime for lids.

Rubbermaid Brilliance Glass differentiates through its universal lid system—lids are interchangeable across different container sizes in the set. Rubbermaid also offers microwave capability with lids on through a venting system, something Razab doesn’t provide.

Razab’s advantage is value. At $31.43 for a set of two large containers, you get borosilicate glass quality at a more accessible price point than premium competitors. If you prioritize capacity and glass quality over lid sophistication, Razab delivers solid performance for the investment.

Final Verdict

The Razab 80oz Borosilicate Glass Storage Containers earn a 4.2 out of 5 rating. They deliver where it counts: durable borosilicate glass construction, generous capacity for serious meal prep, and reliable airtight seals that have performed flawlessly through six months of daily use.

The main caveat is the plastic lid construction, which works well but may not match the longevity of the glass itself. If you can accept this trade-off—and most users will—these containers offer excellent value for meal preppers and home cooks who want to ditch plastic for good.

For large-capacity glass food storage at an accessible price point, Razab delivers.
