Nice Bau Haus clone!
Color: Black
Shockingly nice Bau Haus clone. We'll see how it holds up over time but...appearance and comfort are first rate so-far.

QC Failure
Color: Black
Retro light works aleatory: Sometimes it activates a couple of seconds when button depressed, sometimes deactivated as soon as you release it. A gross quality control failure in a brand-new watch, very disappointing.

Big
Size: One Size, Color: Smoke
Very big! It fits my textbook and laptop, book, switch, wallet etc. It doesnt have a zipper, but big enough for if youre trying to bring all of your stuff with you for the day. The strapnis adjustable as well. Its a beautiful color, great quality, and 3 inside pockets with a zipper on one. A great bag for traveling.
