I purchased this from a handmade site a few years ago. I like the look of it and have taken great care of it, so I've only used it a few times. The base of the shoulder strap hasn't stretched or frayed, so I think it's still perfectly usable. The size is about the same as it would hold two 350ml plastic bottles. I think a mini wallet, cell phone, and small pouch would fit in it with room to spare. Thank you.
