Thank you for viewing. I was a railway consultant, but I have retired and am selling this item as I no longer need it. I purchased this during my consulting days so I could work remotely, but I ended up not using it much, so it's relatively clean. There are no tears, damage, or writing, nor any noticeable stains. However, please understand that this item has been stored by a private individual. If you are not overly concerned about it being a used item, please consider purchasing it. Thank you.
