I didn’t want to have to carry a backpack in order to carry my plastic book case around and I was tires of wedging it between my butt and trousers. Yes, natural selection gave me hands, but those I want to have free. So, I bought a belt at a thrift store, some rivets and that belt lock thingy at a… Store that sells sewing stuff? And voilà. I dunno. Obviously I went with practicality over looks. 😅
