Welcome to the Blockhütte.
You are holding something built to last. Here is everything that goes with it: care, spare parts, and us if anything sticks.

Which product do you have?
Pick yours. You will see how to care for it and which parts you can replace.
Stainless Steel Lunch Box
Not insulated, but leakproof. Dishwasher safe, every part.
Insulated Water Bottle
25 hours cold, 13 hours hot. Without preheating. Dishwasher safe, all of it.
Double Vacuum Insulated Water Bottle

Insulated Food Jar
19 hours cold, 14 hours hot. No preheating, no microwave. The lid is recycled plastic, the rest is steel.

Something not right?
Then write to us. A part missing, something stuck, or you are unsure: we send a replacement.
You have three years of warranty anyway. And sixty days to try everything out.

Help yourself
Care and usage instructions for every product.
Every part on its own.
If the seal gets tired after years, you get a seal. Not a new box.
Lids, dividers, clips, brushes: each one is in the shop on its own. A spare seal came in the box, by the way.
Why we do this
We build things that stay. A box you use for years is a box you never replace.
That is why steel. That is why every wearing part is sold separately. And every year an independent lab checks that nothing is in there that should not be. Lead too, tested under the US CPSIA. The reports are public.
Designed in Hamburg, engraved in our facility in CA. The best day to start is today. From where we stand, you already did.
Now we would like to hear from you
What do you like most? The build, the packaging, the way it fits your day?
