Review: Long term review - Observations after nearly three months of daily use: The lunchbox is well designed and constructed overall. It is a single-walled stainless steel box with a sealing lid that fastens tightly with latches. I was looking for something to solve a problem I created - I bike to work and carry meals in a messenger bag. I needed a relatively flat container that didn't leak because it ends up sideways in transit. This product satisfies that need. The silicone seal and tightly latching lid ensure there are no leaks. As a side note, the description states an extra seal is included in the packaging. I did not receive one with mine. The box is single-walled, so it isn't insulated. The metal is a good enough conductor that things will stay cool or warm for half a day or so, but if you have something that needs to be kept very cold all day long, you'll need to figure that out. Condensation can form on the outside of the box if its contents are cold. The included cloth sack should help manage keeping any condensation from spreading to other items you're carrying like books or whatever, but I have not used it. Other reviews mention the lid can be difficult to open. I have noticed this, especially if there is a temperature change, like putting hot food in the box and then refrigerating it before traveling. Or trying to open it after pulling it out of the refrigerator. Since the seal is airtight, I'm guessing the temperature difference creates a vacuum effect. This isn't 100% of the time and I haven't intentionally tried recreating the conditions for getting the lid stuck, but it's something to be aware of that probably isn't an issue with containers that have screw lids. It can be very hard to open for an adult, so I can see it being very frustrating for a child. There are two removable dividers that allow you to create up to three partitions inside the box. They are also stainless steel and formed to fit snugly inside the contours of the box at any point along its length. In practice, I use one divider to make two decently sized partitions. The dividers fit as well as this design allows for, but are not watertight, so use common sense with these and have realistic expectations. Anything dry will stay separated. Wet, runny, or saucy foods probably will not. On that note, remember this box is a single uninsulated container, so don't expect a cold salad to remain crisp if the other partition has something hot in it. After each use, I separate all the parts and hand wash them individually with regular dish soap. They air dry in a dish rack. I've had no issues with staining or latches sticking or separating. Overall I'm very pleased with this lunch box. It does exactly what was designed for.
Review: Practical and plastic free! - This little container is so much nicer than I had expected - super high quality materials, no plastic junk, well manufactured, lid is super secure and does not leak, and best of all, it goes right in the dishwasher and comes out perfect. I use this to bring home-cooked foods to work and on the road with me in my bag or backpack - doesn’t need to stay upright or be wrapped in plastic to prevent messes… allows me to avoid using plastic, which we could all use a little less of. I will be buying more of these!!

### ⭐⭐⭐⭐⭐ It’s so nice I bought it twice
*by I***Y on January 27, 2026*

We love this box. We use it as the breakfast box for our 4.5 year old in kindergarten. It looks small but the volume is actually larger than his previous bento kids box which is much heavier and bulkier. It took him a few days to get used to opening and closing, but now he has no issues with it. It’s very sturdy, well made and just feels like a great product. We enjoyed using it in the past few months and ordered another one for our younger child. We clean it regularly in the dishwasher and it cleans perfectly without any smells sticking to it like plastic. It’s definitely not cheap but it’s well worth the price. It’s exactly what I wanted. A well made, low maintenance box that is great for both kindergarten and packing snacks or lunch for a trip.
