Readily available anytime, anywhere

Christoph Müller is always prepared for any situation. That's why he has at least four PB 8515 roll-up cases at home – for every occasion.

"We have the PB 8515 roll-up case ready to use at least four times in the house. For all those moments when you need to quickly screw something."

Christoph Müller, Mueller AG  

It has to be quickly available and practical

Christoph Müller completed a commercial apprenticeship and a business management degree and leads Mueller AG in its fourth generation. He grew up with tools, and they accompany him everywhere – throughout his entire life. So, it's not surprising that the 31-piece PB 8515 roll-up case is readily available (he has at least four of them) on every floor of his house, in his workshop, and even in the garage. At home, things need to be done quickly – and there's no time for searching. 

That's why the PB 8515 roll-up case is his number 1: a compact, practical, versatile set that can handle almost any handyperson challenge – and it's something that no business, household, or camper should be without.
