They have all been used but still have a lot of use left.
The first one is a burgundy envelope style. It is a fabric type, I am not sure what the material is, perhaps nylon. It is made by Cobblestones and has black silk lining, with a velcro closure, that spans the entire top. The inside of the bag is in excellent condition, the outside front has a few stains that I think would come out, the back is in excellent condition. There is a 7" inch wrist strap on the left side. This could probably be washed in the washing machine on a gentle cycle. The bag is 16" x 11 3/4".
The second bag is a brown leather type with a zip closure. It is made by Carry Case and has a tree bark look. This one shows a little more use, there is a tear on side by the zipper, that could probably be stitched up. It measures 15 1/2" x 11 1/2". The inside is in good condition.
The last bag is a black briefcase style that is in good condition. It measrues 15" x 11" x 1/4" and is brown with green, red, and white stripes down the front. Inside there is a pocket on one side with a snap tab. The back has a large zipper pocket and the handles are 5" long and 3" high. It is in good conditon, there are a couple of small spots where the piping is tore. It still has a lot of use left in it. I did wash this in the washing machine and it did not hurt it at all.
