Burgundy bag

I bought this bag as part of a set at Wilson’s Leather shop several years ago. I used the large tote bag until it wore out, but never used this bag, which could be used as an insert in a larger tote if you take off the removable strap. When I bought it, the sales lady said it was real leather, but I am skeptical, as I do not see any indication of that inside the bag, nor do I see the Wilson’s name. Leather or vegan leather?? Measurements are in the photos. The bag is in excellent, unused condition.
