Backpack-style laptop case

This is a backpack-style laptop case. I bought it on Amazon.
It's expandable, and when expanded, it can hold items like a water bottle, smartphone, tablet, and wallet.

I originally bought it with the intention of using it as a bag-in-bag PC case inside a carry-on suitcase, and then taking it out to use as a backpack when I only needed to carry my laptop, smartphone, and wallet at my destination for business trips. However, it was too large for my laptop (13.3 inches), so I'm selling it.

I've used it about 3 times as a laptop case, and I haven't used it as a backpack yet.

Thank you for looking.
