Have had one since my first month in business,22 years now.
Mine as stated in ics archives is modified.Longer,with pockets in the inner flap for biz cards,a hole for hoses in lower bottom.Wider sides for better coverage.Greenies, door stop on a lanyard for better security .If you do not carry that doorstop consider it.Worth every penny.
Another item is to be possible wet floor sign laminated also...Mine is the Bane version which is naugahyde,that rare critter seldom seen...
Elastic straps are thicker also.But there are a few minor pockets for a electric adapter,hose hook,etc,also.
My cards are different colors per specialties so it look neat...
I am thinking of making one in black ,the blue looks somewaht faded after 22 years...
But the version shown is quite good as it is,but you know me.I tweak everyting...
