I purchased this in the spring of this year. I have used it a few times. The shoulder strap is removable. Bag size: Height: Approximately 21 cm Width: Approximately 30 cm Bottom dimensions: Length: 11.5 cm Width: 24.5 cm There is a magnet inside, and there is a pocket with a zipper and a pocket without a zipper. There is still room even with a long wallet, mobile phone, and fragment case inside.
