SNUG STARCanvas Handbag Multi-Color Striped Lattice Cross Body Shoulder Purse Bag Tote-Handbag for Women

What is the interior material like? Is it thin and gauzy or more durable? I'm worried about holes developing. Thanks!

Is this machine washable?

Would this be a good school bag?

How long is this bag from top zipper to bottom? the measurements given are unclear.
