I just bought this on Amazon! I tried to use it, but I received a different item, so I am selling it. I only took it out of the plastic bag for the photo, and it has never been used. Although it is described as a waist pouch, it can also be used as a shoulder pouch as shown in the photos. I purchased it as a waist pouch, but I am unsure whether the waist part is attached with my own belt or with an included strap, as it is still new. However, I searched for "waist pouch" on Amazon and purchased it. This is the size from Amazon: Length: 14 cm Width: 2 cm Height: 19 cm Thank you!
