This is L.L.Bean's Rolling Deluxe Book Pack. Erm, sorry for the low rez picture.

I could go into the features of the thing, but really what can I say?

It has wheels and a retractable handle. With time, the handle gets harder to retract. Sometimes pressing the button on the handle gets hard, and usually the handle goes down only halfway. This might be due to contaminates getting in along the shafts or past the button.
