Do the holes line up with standard US 3-ring binders?
Reviewer consensus
On mainstream models from Bostitch, Swingline, Amazon Basics, AFMAT and XOOL, yes — they're set to the US 3-ring standard out of the box. Watch out for adjustable 2/3-hole models: reviewers occasionally report that the head needs to be re-seated firmly, and a handful of buyers note their punch placed holes slightly further from the edge than expected, which can crowd text near the margin.
