This one is made of a thick and sturdy vegetable tanned leather. That works really well for the round shape. It's the same type of leather as I use for the Collapse bags. The midnight Blue that I've recently added, is the Dual leather I use for many other bags in the collection.
Due to its curves, there's quite a bit of volume for this modestly sized bag. All your belongings will sit like peas in a pod in this one.
Dimensions: 24 x 23 x 13 cm, handle drop is a bit over 50 cm, so you can wear it across. Two small inside pockets. There is a blind magnet closure, which is really practical, it falls into place automatically every time you let go of it.
If this one is still a bit big, try the Bobo.
