I can't decide if it's a small or large handbag. I think Goldilocks would say it's just right. My stuff fills it up nicely but there's not a lot of extra room. The measurements are:
15.5" wide at the top, 12" wide at the bottom.
The straps are actually too short to put over my shoulder, so it's just a handbag. The Prototype II that is currently under construction has longer straps. Pictures of the new one will be posted soon! It's made out of the best imitation leather I've ever seen. Hopefully this item will appear in my shop soon!
