After much research good suitcase found!

The Curver XXL is really a great tool case. Wertig processed and it offers enough space, even in the upper part in the removable insert. What I really like the design of on the cover laterally inserted hardware subjects which, if used, are blocked and do not jump by careless opening the main lid and can empty the contents ... this is repeatedly happening with my old toolbox and was always very annoying.
Toll also the rubberized, stable grip, the crate jäßt be comfortable to wear and looks real handy, despite the large proportions.
