Gray inner bag with multiple pockets for easy organization. There are two black ballpoint pen stains on the lining. Please check the photos. There are no other stains. I think it's probably a size M, but it might be S because of a difference of a few centimeters. I'm sorry... The actual photos look navy, but the real color is gray. - Color: Gray - Internal structure: With multiple pockets - Usage: Inner bag, bag-in-bag - Design: Simple and functional Thank you for viewing.
