It is unusable for my purpose. the hole punch may be 1/4 inch, but it is a 1/4 inch on the long side. the short side is maybe a 1/8 of inch. that wouldn't be bad except it only punches vertical holes. I had intended to use it to punch holes for custom inserts for my wire bound planner but it is completely useless for that purpose because only a string could go thru it.
