What type of business still uses briefcases? I guess bankers, estate agents and double glazing or conservatory salespersons. I use my old briefcase to store old important paperwork. Executives love these cases, they are practical in that they are mobile offices, the top can be used as a desk for writing or a laptop, inside can be a host of stationary and files. Todays briefcases are generally made the same as the old designs, but now with better combination locks and laptop straps and spaces. Materials used have changed slightly, most executive cases are made from faux leather, or Pu leather. Making the case in this leatherette is more economical, it looks like leather,is waterproof and is just as strong yet more light weight. The aluminium metal laptop briefcases are also slim line and lightweight, and these are great for modern laptops and MacBooks.
