Hartmann Large Carry On Shoulder Bag or Duffel

21 x 13 x 8 but one compartment expands 2.5 inches.    Sorry, no shoulder strap included.  Two main compartments, plus a front pocket. Also a rear zippered pocket that can turn into a trolley sleeve to slip over a rolling suitcase.  There are a few scuffs on the exterior ballistic nylon, but fabric is not compromised in any way, no issues with seams, zippers are smooth and easy.  Interior is in excellent shape, no issues.  The bad part: the nylon webbing for the handles completely lost color. They should be olive green, similar to the bag material. While in storage they faded to having no color, almost white. I stupidly tried to color one of the straps with a green alcohol ink but the results are not pleasing. It's like grass green or something. I should have left it with no color.  So perhaps you have some experience with this kind of thing and can dye the straps?
