I'm selling this because the size was different from what I expected after purchasing it here. It's a Topologie-style bag ☺︎ Topologie straps can be used with it. ↓ Quoting from the original seller's page below ↓ This is a simple and functional shoulder bag. It comes with a rope strap. It has two pockets, each with an inner pocket. Also, a PET bottle or folding umbrella can fit in the middle. There is also a smartphone-sized pocket in the middle, making it functional.
