This is a sacoche made of unbleached fabric. It has two pockets on the front and one on the back. There is no inner pocket. Plus snap buttons are attached to the main compartment and the back pocket. I think it can also be used as a bag-in-bag. The shoulder strap is not included. The bag itself only. Please use your own shoulder strap. Please consider the following before purchasing: Defect: The tag was caught in the gusset during production. See photo 2. Approximate size: Height: 17cm Width: 25cm Gusset: 3cm Material: Outer fabric: Oxford Lining: Broadcloth
