This is the 2nd one of these I have bought. The ONLY thing I wish, is that the same company that makes these, a few years ago made it in a larger, 6" wide size, but I have not been able to find it anywhere, including where I bought one of those. I use my brief case for my mobile office. I'm a charter bus driver, & I need everything in my briefcase that I can carry (maps, paperwork, pens, correction tape, scotch tape, my medications, absolutely everything thinkable. As you can imagine, that takes space. NO other expandable brief case has held up like these. They have only failed when I have damaged them, but they really take a licking; should be made by "TIMEX" if you know what I mean. I suggested to Customer Service to try and locate supplier that has the 6" cases.
