The wire coil can bind paper up to letter size. For smaller paper sizes, trim the excess wire with scissors.
Durable double-loop metal combs guarantee long-lasting performance. The metal construction doesn't warp easily, and paper doesn't shift easily during binding, making it the first choice for binding important documents.
Especially suitable for the Rayson TD1222 wire binding machine or any 2:1 pitch punching machine.
