I was super lucky to find those old Bülach canning jars in Zürich, and I am happy to share my finding with you! The soup kit include:

-a vintage silverplated ladle with the message of your choice

-a Bülach canning jar of 1L (dating from 1915-1950)...

-...containing 5 different kinds of organic beans, lentils and grain (for now: kidney beans, chickpeas, green lentils, red coral lentils and barley).

Here is a glimpse of the story of those historical jars, produced by Glasshütte Bülach :

The bail closure was completely water tight and as easy to apply and clean as the swing stopper of a beer bottle. In World War II, the wartime economy took over organization of everyday provisioning, overseeing the smallest details of business and private life, and Glashütte Bülach’s product range reflected the spirit of the times. As was to be expected, competitors and product pirates entered the market. But Glashütte Bülach held a trump card - its well known and legendary green bottle was an easily recognizable brand characteristic. (...) In 2002, Glass production at the Bülach plant was discontinued in its 111 th year of operation. Prices collapsed due to internationalization of the markets (...)"
