First the article itself:
The extender tube is supplied in the used Canon Quality. Apart from the obligatory dust covers include a leather bag and an instruction manual supplied. Even a German-language description can be found.

My conclusion:
The purchase is always a good decision and enriched telephoto and macro fans with new perspectives and possibilities.
