Minotaur, Porter, and White M.U.G. Backpack with adjustable straps and a front pocket. - Brand: M.U.G. Minotaur Porter - Color: White - Design: Backpack - Straps: Adjustable - Material: PVC Thank you for viewing. Purchased several years ago and used about 10 times. The condition is good, but there is some discoloration due to aging (around the back straps). There is a faint spot-like stain on the front pocket area. The inside of the bag and the pockets are relatively clean with no noticeable stains or marks. Thank you.
