This portfolio is ultra thin and extremely light weight but this doesn't compromise the quality of the item. The threading appears to be very sturdy and the material is strong. It comes with a pad of paper but the refills are cheap and easy to get. The paper/pad is a standard 8.5 x 11. I was a little worries that the snap on the side would hang out too much and could be an obstruction for the zipper on my briefcase but it fits great. The portfolio also has a divider on the inside of the front panel to store loose leaf pages and two smaller pockets which I use for collecting/storing business cards and for holding my slim cellphone.
