Originally called the Ibico 640ID the GBC MP2500ix is an awesome desktop modular punch that is extremely popular in corporate and print for pay installations. The die sets listed below allow you to use your MP2500ix to punch virtually any punching pattern including combs, coil, wire, Velobind, Proclick or even 3-hole. Simply slide the old die out of the side of the machine and slide the new die in its place. There are no tools or levers required to change the dies. These die sets should last a very long time under normal circumstances. However, please be careful not to punch too many plastic covers at one time which can very quickly ruin your die.
