Where is this sugar box from?

[Stantheman]

Hi! I would like to get to know where this sugar box comes from. I mean country of origin, knowing the city and maker would be even better.
I guess that mark with number 3 is silver control mark for .800 silver purity. Is it import mark? What country used this mark?
Thank you in advance for any information!
