I think that this is a Denim cloth Sash Bag, it seems to be blue mostly with some black and grey tones depending on the lighting. (It isn't actual blue jean/denim, it is a lightweight cloth that was called denim for it's appearance/color.) It is Original Classic size. Very lightweight bag.

I was the second owner but never carried this bag, I am not sure the original owner ever used it as it is in excellent condition and appears unused. No odors. Please review all photos closely for exact condition. The little runs in the cloth are not damage, just naturally occurring dark threads that stand out. If you need more photos or have questions please ask. My home is smoke-free and the original owner's home was as well.
