Hulken Signature Rolling Tote Bag

I first saw a Hulken bag in action when I was tabling at the Seattle Art Book Fair; it stopped me dead in my tracks, because the person using it was merrily whizzing by with honking loads of books (and anyone who has had to schlep a tableful of books knows that it is not usually a graceful process). Upon returning home, I bought myself the medium-sized, shiny, shiny silver version, and it is the handiest thing. It wheels smooth as a roller skate, holds a ton, and folds up fairly flat. A bonus is that it is not so heavy that I can't carry it over my shoulder, so that it presents as a very large glistening tote, allowing me to bring it into places where a wheely cart might catch side-eye.
