The Bierverbond alcohol tester does not run on batteries and is not made of plastic. We go pure nature (just like our beers). So in the cotton bag you will find a nice wooden brainteaser. Do you know how to make the cube?
A wooden brainteaser in a cotton bag. Completely pure nature. Just like our beers. We call it an alcohol tester, because if you can’t get the cube done, you’ve really had one too many. But pay attention, because in court you have a weak case when you use the result of our test. So just don’t drink at all if you still have to go on the road.
