I couldn't tell you...
The company/ league

https://en.wikipedia.org/wiki/Boerenbond

changed the name in aveve and is still selling the things they always did;
http://www.aveve.be/

It could have been anything going from seed, to butter, rope, .... anything farmers could need or produced....

When I found it there was militaria in it! ;-)

 My latest.

The big one is a Jaques chocolat box, the smaller; my guess would be a present (filled with sweets) to commemorate a new born baby( a tradition over here, sweets are (literally translated as) sugar beans....) .

 My pleasure!

Do you have a link, please?

Here is what I got today;

 and this day;...

 My selection for this WE ;-)

 Not that small any more...

Some still have they contented  in it (sugar, buttons, pens, sewing gear etc...)

Some more;

 And particularly like this one.

Seldom seen those big colored coffee tin's.

 Very glad with the new addition.
