These reflex blue spiral binding coils are designed for use in any 4:1 pitch spiral coil binding machine. Made from the highest quality food grade PVC plastic our ColorCoil offers a quality, professional look while binding documents up to 2" thick. Although these particular coils are reflex blue, we carry 4:1 pitch coil in 45 different colors and in sizes up to 50mm in diameter. Plus, all of our reflex blue binding coils are CPSIA and ROHS compliant and are made in either Canada or the USA (not China). Please note that most of our reflex blue 4:1 pitch coil is made to order, is non-returnable and can take an extra 3 - 5 business days to ship. If you need this product in a hurry please give us a call for options before ordering.
