Best Airtight Glass Food Storage Containers on Amazon and Walmart (All Razab Sizes Compared)

Razab glass food storage containers are made from borosilicate glass with BPA-free airtight lids. They go from freezer to oven to microwave without switching containers, they do not stain or absorb odors and they come in sizes that cover single-serving meal prep all the way up to full batch cooking. This post covers every size currently available on Amazon and Walmart, what each one is genuinely best for and which one to buy depending on how you cook.

Two categories. Meal prep sets if you want multiple containers in one order. Large single glass containers if you need one specific size for roasting, storing bulk food or a particular leftover situation. Both are borosilicate. Both have the same silicone seal. The difference is just volume and what you plan to put inside.

Razab Glass Meal Prep Container Sets

These are multi-container sets in multiple size and color options. Good if you are starting from scratch, replacing everything at once or want matching sizes for the whole week. All sets are borosilicate glass, oven safe without the lid and dishwasher safe on the top rack.

30-Piece Glass Meal Prep Container Set in 5 Colors

Thirty containers across two shapes. Rectangular containers at 185ml, 370ml, 660ml, 1040ml and 1520ml. Square containers at 160ml, 310ml, 510ml and 800ml. Round containers in 240ml, 390ml, 630ml and 960ml. That is a lot of sizes in one order.

Who is this for? Someone doing full weekly meal prep for a family or a household where different people need different portion sizes on the same day. Nothing gets confused in the fridge. Nothing ends up in the wrong lunch bag. That is the actual point of the sizes and it works better than it sounds.

The 1040ml and 800ml rectangular containers are the workhorses in this set. Grain bowls, protein portions, full salads. The 660ml handles side dishes and snacks. The small sauce containers prevent the situation where your dressing ends up everywhere inside a bag.

1520ml Medium Glass Container, Set of 2 Available in Different Colors

1520ml is 51 oz or just over 6 cups. This is the size that fits a full single-serving meal: protein, grain and vegetables together without stacking lids or using two containers. The set comes as two containers with two lids.

Best use case is for packed lunches for adults. The rectangular shape sits flat in a bag without tipping. The silicone gasket lid does not leak even if the container is on its side. That matters more than most people realize until they have cleaned their bag after a cheaper lid gave up.

Also available as a set of two with the 2700ml container if you want one smaller size and one larger size in a single order. Covers a wider range of portion needs without buying two separate products. Available in 4 different color options.

18-Piece Glass Meal Prep Container Set, Set of 9

Nine containers with nine lids also have three range of sizes. Designed for households doing five-day meal prep who want enough containers to cover breakfasts, lunches and snacks across a full week without washing containers mid-week.

The set is available at Walmart only and covers multiple sizes and shapes like round, rectangular and square in one order. If you are doing the kind of prep where Sunday produces seven to nine individual portions that all need to live in the fridge until Friday, this is the set that makes that possible without running out of containers by Wednesday.

6-Piece Glass Food Container Set

A starter set. Six containers in matching sizes with locking lids. Good for someone who wants to try borosilicate glass containers before committing to a larger set, or a single-person household that does not need ten containers at once.

Six containers covers five days of lunches with one spare. That is the honest math. If you prep more than five meals at a time or cook for more than one person, you will want more. But as a first set or a replacement set when three or four containers from an older collection have given up, this is the right size order.

Razab Large Glass Food Storage Containers

Single containers in large and extra-large sizes. These are for roasting, storing whole chickens or turkeys, keeping bulk-cooked grains and soups, or any situation where a meal-prep-sized container is not big enough. All are borosilicate, all have silicone-sealed lids. The lids on these are not microwave or oven safe. The glass body is.

A lid that does not seal properly is almost worse than no container at all. Razab's snap-lock silicone gasket lids are the part of these containers that actually justifies the price compared to a basic glass dish with a loose cover. Worth knowing before you buy.

2700ml Large Glass Container, 91 oz / 11.5 cups

2700ml holds 91 oz. That is a large pot of soup, a full rotisserie chicken, a week's worth of cooked grains for two people or a family-sized salad base. It fits a standard fridge shelf without needing to rearrange everything else around it.

The handle lid makes this one easy to move when it is full. That sounds minor until you are pulling a full container out of a 375 degree oven and need something to hold onto. Ergonomics on large glass containers matter more than people give them credit for before they own one.

3300ml Large Glass Container, 112 oz / 14 cups

3300ml is where batch cooking gets serious. This holds 112 oz. A full lasagna, a family-sized casserole, enough cooked rice for five days for a family of four. The rectangular shape fits standard oven racks which is why this size makes sense for roasting as well as storage.

The same container goes from oven to fridge to microwave. No transfer step. That is the practical reason this size matters beyond just volume. You cook in it, you store in it, you reheat in it. Three steps, one container. Less washing, less mess, less going wrong.

3900ml Large Glass Container, 132 oz / 17 cups

3900ml is 132 oz and 9 inches long by 7.75 inches wide. Turkey. Whole roasted chicken. A full batch of soup for the week. Watermelon and large fruit. This is the size that solves the problem of not having a container big enough when the roasting pan comes out of the oven.

It handles temperatures from -40 degrees F to 980 degrees F. That range covers the full chain: freezer to fridge to oven to table. Nothing gets transferred to a different vessel at any point. That consistency matters for food that takes a long time to cook and needs to stay contained the whole time.

6500ml Extra-Large Glass Container, 220 oz / 28 cups

6500ml is the largest size in the Razab lineup available in 4 different colors. 220 oz. 28 cups. This handles a full Thanksgiving turkey, a large watermelon, or a party-sized batch of anything. The handle lid on this size is not optional. It is necessary. At full capacity this container is heavy and the handle makes the difference between moving it safely and not moving it at all.

Most households do not need this size for everyday use. But for the two or three moments each year when a standard large container is not big enough, this is the container that solves it. Roasting a turkey and needing to store the leftovers afterward. Buying a large watermelon and needing somewhere to put the cut pieces. A big batch of lasagna for a gathering.

Not a daily-use container. A very specific problem-solver that earns its storage space when those moments come around. Worth owning if your cooking occasionally goes that large.

Quick Reference: Which Razab Container Do You Actually Need?

Not everyone needs every size. This table maps common use cases to the right container so you are not guessing.

Which Size Should You Start With?

If you have never owned borosilicate glass containers and want to see how they hold up before buying a large set, start with the 1520ml set of two. That size covers daily meal prep for one person and gives you a direct comparison to whatever you are using now. If you prep for a family or want the full week covered in one order, the 30-piece set on Amazon or the 18-piece set on Walmart covers everything without needing to buy separately.

For large storage, 3300ml is the size most households actually need most of the time. It handles casseroles, roasted chicken, batch grains and leftover soups. The 6500ml is the one you buy when 3300ml is not big enough. Most kitchens need one of those moments a year.

All sizes are available directly on Amazon and select sizes are available on Walmart.com. Both platforms carry verified Razab listings with free returns on most orders.
