Glasslock 18-Piece Assorted Oven Safe Container Set

I love this set! I just should have checked the sizes. I could use a few bigger glass containers. Great item! Very durable. The seal is really tight. You can take the leftovers right from the fridge in microwave them. They are very easy to clean. I throw them in the dishwasher. They have a stackable design.

I've had these since 2018 & not a single problem with them until now. I'm a bit shocked by all the bad reviews. I've used these in the dishwasher, the microwave, the freezer. I always next them for storage so Idk why people are saying you can't stack them. I haven't been particularly gentle with them or treated them like they're fragile. I've not seen a single shard of glass this whole time. I don't know if I got lucky or what, but I love these containers. Because I can nest them to store them, they all fit nicely in a drawer. They do a brilliant job of keeping food fresh. I've started chopping a lot of my veggies when I buy them & storing them ready to use in these because they keep & stay crisp so much longer. They can sometimes be hard to close or open, so be aware if you have weaker hand. My 10yr old needs help sometimes, though most of the time he can do it. I've sometimes had to turn it on it's side to get better leverage but it always does what I want it to. I've been really happy with these, I'm only back to see if I can find replacement lids. I put one in the microwave, with the lid offset so it wouldn't get stuck. Except, it slipped into place and got very, very stuck. This has happened once or twice before, but never this bad. It was so sucked in & tight to the edge that after twenty minutes of trying to wedge something in between the lid & edge to break the seal I gave up & stabbed the thing. Let the air out & I'm having my lunch but now I'm down a lid. lol That isn't the container's fault though, that was user error.

Meal prep | 5/5 This set is a meal prep powerhouse. The variety of rectangular, square, and round containers makes it easy to portion out lunches and dinners for the week without feeling restricted by one uniform size. I especially appreciate being able to cook, store, and reheat all in the same glass container (without the lid), which reduces dishwashing and saves time. The clarity of the glass allows me to instantly identify what’s inside, helping me stay organized and avoid food waste. For structured weekly prep or simple leftover storage, it performs exceptionally well. Size | 5/5 The assortment of sizes is extremely practical. With larger 6.3-cup and 3.5-cup rectangles for family-sized dishes, mid-range squares for side dishes, and smaller round containers for sauces or snacks, the range covers nearly every typical kitchen need. I don’t find myself wishing for a different size because the set already anticipates common use cases. The nesting capability also makes cabinet storage efficient. Whether packing lunches, storing chopped produce, or refrigerating soups, the size variety feels deliberate and well-balanced. Leak proof | 4.5/5 The airtight, leak-proof seal is impressive. Once the polypropylene lids are snapped into place, the containers feel secure and dependable. I’ve stored soups and saucy dishes without worrying about spills in the fridge. The locking tabs provide a reassuring snap that indicates a tight seal. While I would not intentionally shake them upside down for extended periods, they handle normal storage and transport very well. The seal also helps maintain freshness longer, which is noticeable with leftovers and prepped ingredients. Sturdiness | 5/5 The tempered glass construction feels thick, solid, and durable. These containers do not feel fragile or flimsy; they have a reassuring weight that suggests long-term reliability. They transition well from refrigerator to microwave or oven (without lids) and clean up beautifully in the dishwasher. I have not experienced chipping or cracking with careful, normal use. The lids are flexible yet sturdy, and the locking tabs feel strong without being overly stiff. Overall, the build quality gives confidence that this set will last for years. Looks | 5/5 Visually, these containers are clean, modern, and minimalist. The transparent glass combined with the streamlined lids gives a polished, organized appearance inside the refrigerator. I enjoy opening the fridge and seeing neatly stacked, crystal-clear containers instead of mismatched plastic tubs. The design feels timeless and functional rather than trendy. They are attractive enough to bring directly from the fridge to the table when serving leftovers, which adds convenience and a cohesive look to meal presentation. Food capacity | 5/5 The total capacity across the nine containers is generous and well distributed. Larger containers easily hold full casseroles, pasta dishes, or batch-cooked proteins, while the smaller ones are perfect for fruit, dips, or portioned snacks. The depth of each container makes efficient use of fridge space without being awkwardly tall. I appreciate that the 6.3-cup size can handle substantial quantities, making it suitable for family meals. For a single set, it provides impressive flexibility and sufficient volume for a wide range of food storage needs. Pros - Excellent size variety for versatile storage - Oven-safe and microwave-safe glass (without lids) - Airtight seal keeps food fresh - Crystal-clear visibility reduces food waste - BPA-free and recyclable materials - Sturdy, durable tempered glass construction - Stacks and nests efficiently for cabinet organization Cons - Lids are not oven or microwave safe - Heavier than plastic alternatives

Good quality/definitely seal well once you get them closed, but getting all four locked can be a hassle. They're also pretty heavy. Awkward to stack because of the various shapes not really fitting into one another. I would keep looking/wish I would have returned them, but they seemed good at first.

At fist I was confused because it said 18 pieces, and I thought they were 18 containers with their lids... Nope. It turned out that those 18 pieces included the lids, so you get 9 containers with their lids. Anyways, I have about a month of using these containers and I am glad I got them. I haven't tried putting them in the oven, but I can say they are sturdy (one of them fell down and didn't break). Lids are a bit hard to snap on, so be careful if you have a disability.

I've been using these for over 10 years, always throwing them in the dishwasher. These seal very tightly. A little difficult to close at first, but they are air tight without a doubt. The lids even hold up well in the dishwasher. I've only had 1 tab break off in all the years I've used them. I use them on a daily basis and I keep buying more. The glass portion also works well in the microwave and the oven.

Great product. Conteiners are very good sizes for different food, they are not too big and not too small. Perfect!

awesome product, loved it

Superb product! After a lot of frustration buying containers with bad lids (Anchor being one brand), we truly enjoy carrying all type of meals (liquid or solid) in the Glasslock containers. The seal is fantastic: simply no leaks! You can even take the gasket off to wash the tops more thoroughly once in a while (although food does not seems to get in the spaces for what I could see). The glass bottoms are sturdy and would not break easily. The sizes offered are convenient for packing lunches and snacks, and they can be nested for storage. I highly recommend this!

Llevo usando estos refractarios por bastante tiempo. Su función de cierre hermético es excelente. Algunos se han caído de altura baja en la mesa (por descuido) y no he visto ni una fractura. Los compré para mi familia, para poder organizar nuestro refrijerador y mantener nuestra comida más fresca y sin mezclar olores. El precio es excelente. Los he visto más caros en otros lugares.

Sehr gute Glasbehälter die wirklich dicht schließen, schade das das Sortiment immer weniger wird. Kaufe sie gerne nach.
