The lunch box and the vacuum insulated water bottle, sized for a day out rather than a desk. Food that survives a backpack, and a drink that is still cold when you stop walking.

Lunch box: two removable steel dividers, silicone seal, travels sideways without leaking.

Vacuum insulated water bottle: 25 hours cold, 13 hours hot, no preheating. Wide mouth, so ice fits and the brush reaches the bottom.

Both are 18/8 food-grade stainless steel, uncoated inside, BPA-free and dishwasher safe. Nothing in the drinking path but steel and silicone.

3-year warranty, and every part of both is available separately under spare parts. Both can be laser-engraved. See individual engraving.

Is it tested for lead?

Yes. Every item in this bundle is independently tested for lead under the US CPSIA. We retest every year. You can download the current reports on our certificates page. No form, no account. All seals are food-grade silicone, BPA-free.

Does the thermal coating come into contact with the contents or me?

No. There is no coating on the outside you touch or on the inside. The thermal coating sits on the outer wall of the inner body and consists of a copper layer. Your food and your drink only ever touch food-safe 18/8 stainless steel.

Which of your products are thermally insulated?

The water bottles and the insulated food jar. Bottles hold 25 hours cold and 13 hours hot; the food jar holds 14 hours hot and 19 hours cold, all with no preheating. The classic lunch box is not insulated.

Can I personalize my product?

Engraving is available for the lunch box, both water bottles and the insulated food jar. The travel mug and the salad bowl are not engraved. Order by 1 PM PT and we engrave it the same day, in our own facility in CA.

Is everything dishwasher safe?

Yes, every product and every part of it. Take the seal out once a week so it dries fully.

Is it leak-proof?

Sauce, dressing and yogurt stay in the box, even sideways in a bag. Thick stews travel fine on their side. Clear soup travels upright.

Can your products be microwaved?

No. Like all stainless steel, they are not microwave-safe. You can put the lunch box in a conventional oven, but take the seal out first. It would melt.

Frequently bought together

Through our extensive travels in the past, it became even more important to us, for environmental and cost reasons, to always have something to eat and drink on hand. We opted for stainless steel lunch boxes and water bottles. However, these products were of inferior quality: either they were made of cheap stainless steel, were not food-safe, or they leaked. This set our goal: to bring the best lunch box to the market in terms of sustainability, quality, and value for money.

Leak-proof for everyday food

You surely know how annoying it is to constantly clean your bag because the old lunch box has leaked again? We do too. That is why we widened the seal and reinforced it. Sauces, dressings and yogurt stay in the box, even when it travels sideways in a bag. Thick stews travel fine. Clear soup travels upright.

Extraordinarily Safe

Every lunch box is equipped with our unique & fully rolled safety edges. This ensures that you and your loved ones will not suffer any injuries. (ATTENTION! These edges are exclusive to Blockhuette.)

Fast Shipping

Your order ships from within the US. Ground delivery takes 2 to 5 business days in the contiguous US.

Most orders are processed within one business day. Alaska, Hawaii and the US territories take 10 to 14 business days.

Every package goes out with USPS, FedEx or UPS, whichever gets it to you fastest.

Recyclable & Plastic-Free Packaging

Sustainability is a top priority for us! For packaging, we have opted for sustainable and recyclable cardboard. Even with the cardboard, we ensure that as little material as possible is used, to save resources.

Food-Safe & Taste-Neutral

Your food touches nothing but steel. The inside is uncoated 18/8 stainless steel: no coating, no aftertaste.

The seals are food-grade silicone, BPA-free. Which lab report covers which product is on our certificates page. Free to download, no form.

Stainless steel lunch box: leak-proof - everywhere

Tired of using supposedly leak-proof stainless steel lunch boxes, only to find they don't hold up? The alternative, plastic lunch boxes, may contain harmful substances like BPA & BPS. At Blockhütte, we are committed to creating the best possible products for our customers, which is why we've put extra effort into our stainless steel lunch boxes. We've improved the closure, seal, and the guidance of the seal. Our community's feedback has been overwhelmingly positive, highlighting that it's the small details that make a big difference. No more worrying about a messy bag due to a leaky lunch box.

Less plastic, on purpose

We believe that the environment will recover from its current strain if we reduce waste. We want to provide you with products that are easy to use and of high quality. By using sustainable everyday products and making conscious decisions, we can reduce our average plastic consumption from 40 kg per year. For our stainless steel lunch boxes with three compartments, we've chosen to partner with the Plastic Bank project. Plastic is collected at international hotspots such as Haiti, Indonesia, and Brazil.

Blockhuette has the best stainless steel lunch box

Yes, self-praise is no praise, which is why we rely on independent reviews from comparison platforms like www.Vergleichen.org, where we were named the comparison winner. This is due to our unbeatable quality, as well as our excellent customer service and the useful extras that come with your leak-proof stainless steel lunch box, such as two dividers or a transport bag. We are confident in our quality and offer a 3-year warranty on all stainless steel lunch boxes. Why wait? Trying is better than studying.

Advantages and Disadvantages of Stainless Steel Lunch Boxes

A stainless steel lunch box has many advantages over other materials. Stainless steel lunch boxes are oven-safe. Stainless steel is extremely durable and heat resistant. You can prepare your food in stainless steel lunch boxes in the oven. The stainless steel lunch box can be used for baking, or even to make lasagna. Stainless steel is a better choice than plastic because it does not contain BPA. They also do not contain any other plasticizers or binders like melamine, which is often found in bamboo dishes and lunch boxes. Microplastics will not get into your food if you scratch the bottom of a stainless steel lunch box with a fork. Lunch boxes made of stainless steel are almost indestructible with daily use. They can withstand extremely high and low temperatures without damage. They can be dropped from high places. They can survive falls from great heights and do not rust.

Hygiene and effects on humans

The hard and smooth surface of stainless steel is easy to clean. Its smooth surface is resistant to microorganisms and does not become cracked or brittle under constant use. The Hygiene Institute of the University of Leipzig found that bacteria are more likely to die on stainless steel surfaces than on plastic. Moreover, stainless steel lunch boxes are much easier to clean than those made of plastic or glass. Stainless steel has no adverse effects on human health. Since bacteria find no place to multiply on the surface of stainless steel, it is extremely hygienic. Additionally, when properly processed, stainless steel is also safe.

Stainless steel lunchbox for kids

We have the right size or bundle for everyone, no matter the age or purpose. You decide which size is best for you. It turns out that the 800ml stainless steel lunch box is ideal for children or for a small appetite at school. The 40oz lunch box is perfect for long school days and a well-deserved break at work.
