The two bags below are bootleg library bags. They’re basically designed to hold books. There are 2 panels sewn together, with draw strings pulling through the top of the bag, looping down to also act as the shoulder straps.
If you’re ok with bootleg items then I suggest them. They’re not the BEST quality ever depending on who you buy from, but they’re ok to use. You may find that the colour will ware away around the draw string pull.
Typically the bags are made so that the same picture is on both sides of the bag. In this entry there are TWO different bags shown.
