Used Thule brand laptop attaché over-the-shoulder case with handles and a removable shoulder strap. Designed for 12 3/4 inch by 9 inch Macbook Air, and can likely fit other laptops or tablets of a similar size. Has a hard, black outer casing presumably made of polyurethane. Inside contains a strap for securing laptop inside the case, as well as a mesh pocket for carrying a charger, and fabric pockets for carrying large pieces of paper or smaller notecards respectively. Although the case has some scuffs and scratches due to years of use, this does not affect the usage of the case in any way. Both zippers are still fully functional, and designed so that you can attach a lock to keep your device secure. This case is extremely durable and will protect your laptop or other device from falls. The case is most likely water resistant, as my laptop has never gotten wet from the rain when inside the case. While it might be able to keep your laptop safe from shallow puddles, it is NOT waterproof and will not protect your laptop if it is submerged in water. I am selling it at the approximate price it was when I originally bought it years ago. This is for two reasons: 1) this item was cheaper back then than similar items are being sold for now, due to inflation; and 2) I feel that even though this item is not brand-new, its sheer durability and quality warrants the price. However, if similar items from the exact same brand are available brand new at a lower price than what I have listed, I am willing to negotiate the price.
