HKJ Chef Glass Meal Prep Containers, Borosilicate Glass

Quick overview

Borosilicate glass is the defining feature of these meal prep containers: the set is designed to move from food storage to reheating or oven use, while the lids help keep packed meals contained during transport. You get 10 containers in two sizes: five large 35.1-ounce containers and five small 12.5-ounce containers.

That split is useful when a full meal and a smaller side, snack, or portion need different-sized storage. The containers are also described as freezer- and dishwasher-safe, and they nest inside one another when empty to take up less cabinet space.

How to use it

Use the larger containers for prepared meals or leftovers, and the smaller ones for sides or modest portions. For example, you could pack a main dish in a large container and a smaller serving of vegetables in a second one, then take both to work. The locking lids have a silicone seal and are described as airtight and leakproof, which is intended to help reduce spills in a lunch bag.

For reheating or oven use, remove the lid first. Keep in mind that the lids are not heat-resistant, so they should also be removed before putting the containers in the dishwasher. The product description gives a temperature range of approximately -4°F to 752°F for the glass, it does not specify separate temperature guidance for sudden changes in temperature.

Practical tips

The two sizes give you more flexibility than a set made entirely of one container size, especially if your meal-prep routine includes different portions or mixed leftovers. Five of each size can support preparing several meals ahead, though whether that covers your full routine depends on how often you cook and how much food you store. The containers are stackable for storage and nest when empty, a helpful distinction when refrigerator space and cabinet space are both limited.

If you plan to carry soup or another liquid, the locking lid and silicone seal are relevant features, but pack the container upright rather than treating the leakproof claim as a reason to toss it loosely into a bag. Glass also has a different trade-off from lightweight plastic: it can be convenient for reheating and food storage, but it adds a rigid item to a work or school bag. The listing does not provide the containers’ dimensions or weight, so those details may matter if your lunch bag has a tight fit.

Practical doubts

Can the lids go in the microwave or oven? No. The description says to remove them before microwave, oven, and dishwasher use, and states that the lids are not heat-resistant.

Are there two container sizes? Yes. The set includes five 35.1-ounce containers and five 12.5-ounce containers.

Can the containers be used for freezer storage? The glass containers are described as freezer-safe. The listing does not give specific guidance about filling limits or temperature changes, so avoid assuming details that are not provided.

Is it worth it?

It suits you if you want a reusable glass set for preparing, storing, and reheating food, and you’ll make use of both larger and smaller portions. The oven, microwave, freezer, and dishwasher compatibility of the glass gives it more utility than a storage set intended only for cold leftovers, while the stack-and-nest design helps when the containers are empty.

Not the best choice if you need lightweight lunch boxes or expect to heat food with the lid on. The missing dimensions and weight also make it harder to judge fit for a particular lunch bag or refrigerator shelf. Choose this set when glass and two portion sizes match your routine, choose a lighter, single-size option if portability or uniform portions matter more.
