This is a faux-leather fully lined sleeve from Proporta. It’s an uncomplicated offering, as this is not pretending to be anything other than a simple, functional sleeve. They could have left it plain, but they’ve gone and put a stripe across one corner on one side only. Not sure why, I think its called style. I guess if it’s your bag, it’s your bag. Each to their own. It comes in a variety of colors so you can mix and match. Keep bringing it!
