Wow, what a lovely pen roll this is. I've tried several others prior to landing on this one, and all had their various shortcomings. This one is just right in all respects. The quality is superlative, and it's quite handsome, as well. I have one with 8 pen slots and am surprised at how compactly it rolls-up. The soft lining for the pen pockets is great. If I could change but one thing, it might be to make the pockets just a tad shallower, so shorter pens don't disappear quite so far down. It's not a big deal: it's quite easy to retrieve them with a little squeeze at the bottom of the pocket.
A great roll -- I haven't seen anything else quite like it. I will likely get another one at some point.
