Black+Blum Stainless-steel Lunch Box | Leak-proof Oven Safe Plastic Free Meal Prep Lunch Food Container, Olive, 1000ml / 34 fl oz

This product exceeded my expectations. The materials are very nice. It's very high quality. The seal on it is awesome!! Like others have mentioned, when you first try to open it it can be a little tricky, but once you get the hang of it, it's not hard at all to open. The only thing that makes it hard to open at all is because it seals so well, which in my opinion is perfect! It's very lightweight and yet at the same time it's nice and solid. The metal is not flimsy or thin. Obviously the stainless steel conducts cold very well in my cooler. So once it goes in there it's airtight and kept at a very cool temperature. I don't really see anything to be improved on with this.

This thing is the perfect size: big enough for a salad or sandwich that will actually fill you up but not too big to fit in a briefcase or bike bag. The materials are extremely solid and the quality is high. The divider is a nice feature too. I have never had a leak even when carrying it sideways but I wouldn't push my luck by packing soup or something.

I have bought at least half a dozen different stainless lunch boxes over the years and this is by far the best. I'm a flight attendant and I've had problems with others either leaking or sealing closed due to pressure changes on the aircraft. I've also had latches break on others. This design fixes all those issues. The pressure valve and silicone seal work perfectly. if I'm carrying soup I use the silicone band just to be sure but I haven't had the container open when carrying other food so I don't think its much of an issue. The steel is also quality. The only thing that could be better is if I had found this before buying the others.

Leakproof, roomy stainless steel lunchbox. In love with this, hence my fourth purchase from the company. Black + Blum looking for testers?

I find this storage method perfect for cold lunches. Compact and secure. Good quality and materials.

Alright, so this is expensive for just one container. However it's good quality material all around. The one thing I will say, if you are NOT the person who opens the pickle jars of your family, then this won't work for you. This thing is a struggle to open and I thought all the other reviews that said this were just weaker folks. I have pretty decently strong hands and this one is tough to open while not spraying your food around because you had to muscle it to get it open. Great quality. A bit pricey, if you're looking for leakproof then this is one of many options but if you have weak fingers and weak grip, you won't be happy with this item

Love it! I travel for a living and this is perfect for putting in the oven and the microwave as well. Great for storing fragile items in a cooler with other items.

My husband is an flight attendant and loves this for work. Nothing spills from it and it is the perfect size for meals. He puts it in the oven and it heats his food to perfection. The only negative is that it is very hard to get the lid off.
