Specifications

Genuine James Burn tooling from Mid-State Litho

This die is genuine JBI tooling, not a compatible copy, so it seats and registers correctly in the Docupunch Plus. As a James Burn dealer, Mid-State Litho supplies the die with dealer pricing and can help you match the right hole pattern to your binding element. Browse the full James Burn binding equipment range or the wider bindery and finishing category, and compare the 2:1 square-hole sibling die (26 holes, 6x6 mm) if you run a coarser 2:1 pattern.
