I finally found a lever arch binder in US Letter size. Everything about it is better than our typical (in US) 3-ring binders. Why are they so hard to find here? (Without switching to A4 paper and annoying everyone around me, that is). Is there a petition I can sign?

@jack I half-heartedly want to speak up for the D-ring, but now I want the one you've got. The front cover has little hats for the arches! ....yeah, that lever arch is nifty.
