A 1L lunch box that makes it easy to organise your lunch and presents your food beautifully.

It might look like a simple product, but this hides the huge amount of design thought and testing that went into creating it. Black & Blum took inspiration from Japanese Bento boxes that offer a design master-class in how to celebrate and present the food they carry. This new design took all the best bits of the original design and improved on them. The design adapts and allows you to carry a huge variety of different foods with ease, all organised, leak proof and a pleasure to eat from. The aesthetic is a clean, timeless look that will age well and stand the test of time. While the world might be seeing a backlash to single use plastic, this design used high-quality, built-to-last polymers for all the right reasons that make the design lightweight, durable, leak proof and perfect for on-the-go.

  • Microwave* (see Spec below), dishwasher and freezer-safe

A leak proof sauce pot can hold your salad dressing or sauce separately until you’re ready to use it (no more soggy salads!). The optional inner dish is an easy way to partition and microwave separate parts of your food. So, for example, you could have hot vegetables with a cold salad.


One of the clips allows you to hold your stainless steel fork on the outside of the lunch box if you don’t take the inner dish.


The lid of the sauce pot allows you to carry fresh parsley or parmesan cheese so you can dress your food perfectly just before you eat it.

Is the Lunch Box microwave-safe?
Yes, the Lunch Box is microwave-safe. Remove lid before microwaving. Two minutes maximum in one go. Stir and repeat if further heating is required.

Is the Lunch Box dishwasher-safe?
Yes, the Lunch Box, inner dish and sauce pot are all dishwasher-safe, please place them on the top rack.

Can the Lunch Box Original go in the freezer?
You can put all parts of the Lunch Box Original in the freezer, but be careful not to overfill as liquids expand when frozen. Always make sure to fully defrost before placing it in the microwave.

Is the Lunch Box BPA and BPS-free?
Yes, all parts of the Lunch Box are BPA and BPS-free.

I can’t open my Lunch Box Original?
You will find a vacuum release gap on the side of the lid where the seal is exposed. Use the back of the fork handle to press the seal, allowing air to come into your Lunch Box. Be careful not to use any other sharp tool to do this as you may cut the silicone seal and damage it.

Is there anything I can do if the product starts leaking?
Firstly, check the silicone seal. If it has been compacted, this might cause it to leak. You can also pull the entire seal out, and push gently back in again, ensuring no one area is compressed too tightly. Remove, clean and fully dry your silicone seal regularly to ensure your Lunch Box stays 100% leak proof.

My food has left a stain on the product, how can I remove it?
Foods like tomato sauce can leave a stubborn red stain, but these can be removed by simply applying bicarbonate soda to a damp cloth and cleaning the affected area. You can repeat this cleaning method several times if the stain is quite engrained, and it should fade over time. It’s also useful to clean the stain as soon as possible before it becomes too strong. However, please note if there is an area scratched or cut by a knife, stains will be particularly difficult to remove, but they will fade over time.



'We launched our first lunch box design in 2010 and this helped inspire and ignite the whole marketplace for food on-the-go. At the time, although the Japanese were using beautiful bento boxes, the West was making do with standard waxy plastic food containers. Today, the market is transformed and far more aware of the eco, health and financial benefits of taking your own food with you. So much so, that we are now seeing a growing trend of people meal prepping and batch cooking. This might be people following a certain diet for health or fitness, trying to live more sustainably or simply saving money. From a design standpoint, we saw this as a great opportunity to create a range of food containers with different volumes and shapes to suit the individual user and food type. The design is simple and minimal; stripped back to the bare essentials to allow it to be competitively priced but remaining truly functional.


Founded by a man on a mission to rid the world of single-use plastic bottles and take away containers, Dan Black leads the design team at Black+Blum, and has done for over 20 years. His single goal is to create products which are functional, innovative and most importantly, made to last.
