BLACK + BLUM Microwavable Stainless Steel Lunch Box | Multi-Function, Vacuum Sealed Container for Healthy Food | Portable and Stackable Food Storage for Office and Outdoor | 40 oz / 1200 ml

I've used quite many types of lunch boxes/bentosand THIS is the best!Simple/microwavable/leakfree/right size to carry

I'm genuinely shocked that there aren't more reviews for such a well-designed and useful meal prep container – this thing is the real deal. I haven't tested the microwavability (although I've read up on the tech and it makes sense to me, it still feels like a crazy thing to try to do with stainless steel - maybe one day), but these things are virtually indestructible (unlike even the best glass or plastic containers), and yet can still go straight from the freezer to the oven up to 428 F (220 C) according to their support, which is perfect for my needs.If you're looking to get away from plastic for leftovers or meal prep, but want something that isn't prone to chipping or breaking (unlike glass), or randomly exploding (tempered glass), then stainless steel is the way to go. I bought these at the same time as a bunch of comparable stainless steel meal prep containers from Bentgo (essentially the only other company you can get "microwavable" oven-safe containers from in the US without relying on sketchy 3rd party sellers or importers) to compare, and by a landslide the Black + Blum containers came out on top.Pros:1. Build quality is pretty good - the stainless steel feels great and has good fit and finish, and the lids are sturdy and well-built2. Lids are really easy to remove (as long as you unlock the valve in the lid) - you just need to hold down on the exposed metal lip of the container below, while pulling the lid off, and it doesn't take too much force to do. I find these lids much easier to remove than most comparable airtight food containers (unlike the Rubbermaid Brilliance, for instance). They're also not too hard to put back on, other than the 1 con below.3. Containers stack pretty well when filled with food4. They come with a 2 year warranty!5. The lids are well and truly leakproof, unlike their competitionCons:1. It's a bit annoying to have to remove the silicone seal from the lid for cleaning, and you do need to remove it to be able to clean the lid. I would've preferred a design like the Rubbermaid Brilliance where the seal is attached to the lid but still easy to clean. The lid in general has a good number of nooks and crannies (thanks to the vacuum seal) that make it trickier to clean than I'm used to.2. Because the base of the container is so rounded, it can wobble around and tip over a lot when you put the lid on if you don't hold it down in the right way.3. Also because the base of the container is so rounded, the containers can jiggle and wobble when stacked on top of each other. It doesn't seem like enough to make the stack unstable, but it is enough to be weird and annoying.4. I really wish the lip was bigger (like the Bentgo Heat & Serve containers) – it would make it so much easier to take the lids off. It's still not too difficult even with the narrow lip on this container, but it could've been made so much easier.Considerations:1. I'm not sure how well the plastic lids handle heat since I haven't dared to try microwave the containers yet.2. I don't know if these are still the best oven-safe stainless steel food storage on the market in countries outside the US – from my research, you're much more spoiled for choice on this front in parts of Europe and Asia.

I do like the look of these but they are very difficult to open if you heat something up and then put the lid on despite the release function

Cooking times an issue for microwaves

Works great, simple food storage

Good quality bowls . Looks bit like a dog bowl mind you .!

Piccola ma abbastanza capiente per un pasto sostanzioso. Io ci faccio stare 150 g di riso senza problemi.. Costruzione impeccabile, non certo economica ma vale i soldi che costa

I find this container extremely good for my work lunch. I can use it for salads etc. Also good if I want to take a jacket potato and microwave it at lunch time. I can microwave it in the container, as it’s microwave safe. Works very well and is good quality.

Very pleased with this container- i keep my little doggies raw food in this as keeps it very chilled in bottom of the fridge. It’s frozen food & keeps frozen all day long! So if needed for lunch no worries as it remains very chilled & added bonus of being microwaveable. Very pleased with this and the lid has a good seal.

This is a sturdy food container that doesn't leak at all. I love that it works in the microwave, although it does take slightly longer to heat food up compared to a plastic container but that's not an issue for me. Dishwasher safe, there is nothing I can pick fault with. I would recommend
