Paper Punches
Spacing is what ties a punch to a filing system, and a set of sheets punched to the wrong centres will not go on the rings at all. Settle that against the binders you already own. Capacity is the second figure and it is a maximum rather than a working number, so a punch rated at its limit every day will wear and drift off square. Adjustable guides help. See two hole punches, heavy duty punches and binders.
