a very successful puzzle

I've seen this jigsaw puzzle or this kind in the business before.
These circles were but out of print and only available as a test model.
The pieces feel very well (3mm thick) and they have designs.
Packed is the puzzle in a pretty printed paper box.
They are printed very similar from both sides, what the puzzle yet
makes interesting. Sometimes you sometimes look for shapes colors and lines.
It's a great activity for young and old. (From about 10 years, I think)
That was certainly not the last puzzle of this kind for me.
