This is a rather old design, but I've only used it 2-3 times and have kept it in storage since then. There are no scuffs on the corners, and I've regularly maintained it with oil, so it's in very clean condition. This is just my personal assessment, but the size is approximately 20 cm wide, 15 cm high, and the strap is about 1 meter 20 cm long. I hope you like it. It also comes with a storage bag. The depth is 5.5 cm, not including the front pocket.
