Jaes Leather SatchelSKU : TZ2360580
A satchel also known as side bag is often with a strap. The strap is often worn so that it diagonally crosses the body, with the bag hanging on the opposite hip, rather than hanging directly down from the shoulder.
They are traditionally used for carrying books and mini tablets as well as whatever that gets to fit.
The Jae Satchel comes with a mini wallet and is sold as a whole.
