Bento Box

This bento box is incredibly well-made and feels very durable right out of the package. The sturdy construction and solid latches immediately stand out, making it clear this is designed for everyday use. I appreciate the quality of this product. The materials feel high-quality and thick without being overly heavy. The compartments are well-formed and hold their shape nicely, and the sealing edges feel secure and reliable. It has a superior build compared to many standard lunch containers I’ve used in the past. I’m impressed with the design and functionality of this product. The divided sections are thoughtfully sized, making it easy to pack a balanced meal without foods mixing together. The secure lid and tight seals help prevent leaks, which is especially important for sauces or juicy fruits. The locking mechanism feels strong and easy to use at the same time. This product is a great value for the price considering the exceptional durability and practical design. I’m very satisfied with the performance of this product after multiple uses and washes—it holds up well and continues to seal tightly. I would recommend this product to others looking for a high-quality, durable bento box for school, work, or meal prep. It offers exceptional functionality and reliability in a sleek, easy-to-use design. Read more

Great quality, leakproof lunch box!

This stainless steel lunch box is great for anyone who wants a durable and leak proof container for meals on the go. It has 3 separate compartments with silicone seals and a tight fitting lid, so liquids and sauces won’t mix inside or spill outside. I really like the portable design and you can even add a thin ice pack or warming pad under the removable tray, to help keep your food cool or warm. This lunch box is excellent quality! It’s made from food grade stainless steel, is BPA free and very sturdy. It’s perfect for both kids and adults. Cleaning is simple since the tray is dishwasher safe, and the secure locking latches make it easy to carry without worry. Overall, I feel like the price is an excellent value for the quality and convenience of the lunch box! Read more

Very pleased with this!!!

I picked up this stainless steel bento box for everyday lunches and it’s been great so far. The size is just right—not too big, not too small—and the 3 compartments make it easy to pack a full meal without everything touching. The stainless steel feels solid and well made, and I like that it doesn’t hold smells or stains like plastic containers do. I’ve tossed it in my lunch bag a bunch of times and haven’t had any leaking issues. It seals up well and stays closed. I use it for work lunches, but it would be perfect for kids’ school lunches or taking food on the go. Cleanup is easy since it’s dishwasher safe, and it still looks brand new after several washes. Overall, it does exactly what I wanted it to do. Simple, sturdy, and easy to use. I’d definitely buy another one. Read more

The Definitive Version of This Box

My family has been using this style of lunchbox for over a year now. Before this, they were all two pieces, which have been great for keeping items separate, but the wear on the bottom pieces looks bad. They are sometimes impossible to clean, especially if they were "forgotten" over the weekend. The removable stainless tray has eliminated that problem. This version has all the benefits of the all-plastic version but is 100% easier to clean. Everything still stays separated and fresh without losing a noticeable amount of space. You still have the space to pack a good-sized lunch for your kids. The lid and attachment hardware are also improved over the all-plastic and seem to be better in this version. This isn't really an insulated box, so you're still going to need a cold pack to keep your food chilly. If you're on the fence about which lunchbox to get, this is the one you want. Read more

No leaks - easy to clean. Sized for kids or snacks.

I love that the food in this lunch box is held in a stainless steel container instead of plastic. It's easy to clean - by hand or in the dishwasher. The seals are great - nothing leaks between the compartments or out of the box! And the seals can be removed for better cleaning. It's an interesting size - great for a younger kid's lunch or to holds snacks for an older kid. I do wish I could fit a cold pack into the bottom so that it could be a stand-alone unit. As it is, we pack this inside a standard lunch box with a cold pack. Overall, I think this is a quality item at a good price point. Read more

Love this product!

The quality of this product is impressive. It is durable and well-made, but still light enough and easy to transport. I have been swapping out my plastic products so I am excited to switch my current bentos for stainless steal. The price is a bit high, but all bento boxes are across the board in my opinion. The size is perfect and the picture I took shows it next to a stick of butter for reference. The lid goes on and off easily and it is easy to clean. I am definitely satisfied with this product.

Easy to open and leak proof

I really like this stainless steel bento lunch box for both my kids school lunches and my own office meals. Its 25oz size with three leakproof compartments keeps wet foods like yogurt or fruit separate from dry snacks and sandwiches so nothing mixes or spills in the bag. Made from stainless steel its durable dishwasher safe and easy to use and open with simple latches even for little hands plus it feels sturdy after daily use without any dents or wear. Great value for picnics or outdoors too since it stays fresh all day Read more
