I like to organize tool by job or function -lrb- electrical , plumbing , etc -rrb- . it make it so much faster to grab tool to go fix something . this bag hold lot of stuff , with pouch on the inside and outside . there be a optional shoulder strap , and even a way of secure a level -lrb- which be usually a pain -rrb- . I like bag much more than metal tool box , as they do not slide around the truck as much . they also do not rust or dent -lrb- then you get to fight with the lid -rrb- . the material bb use to make these be pretty tough . I have a few of they thing that be at least 10 year old , and they be still in good shape . a professional tradesman would wear they out faster , but they should still last for year . this bag do what it should , and it could obviously hold thing that be not tool . I be think of get one for luggage .
