These trade show display shipping cases are manufactured primarily for shipping the folding panel type trade show display.  They have all steel hardware including the spring loaded handle that is located opposite the built in wheels as well as all buckles that are used to tighten the 2" nylon straps that hold the lid closed.  There exists a plastic label pad on which you can adhere shipping labels.  These pads are designed not as a slide in evelope for the shipping labe but rather a place to adhere self adhesive shipping labels because the nature of the durable polyethylene material that is used in the manufacture of the case does not allow aggresive adherance of shipping labels.  The advantage of this is that you don't end up with an unsightly case full of unremovable shipping labels.  Alway use the plastic label plate for placement of your shipping labels.

These shipping cases are produced with a thermo molding process and are empty inside.  It is not recommended that they be use for shipping computers or sensitive electronic equipment.  Again they are designed for shipping folding panel trade show displays.
