Using this CSM Core Medal Combination Change Set is a breeze. First, make sure you have a CSM OOO Scanner (keep in mind the cracked Taka medal won't work with it). Then, simply insert the medals into the scanner to create different combo changes. It's a lot of fun experimenting with the various combinations. When it comes to maintenance, keep the medals in a dry and clean place. Avoid dropping them or exposing them to extreme temperatures. If they get dirty, you can gently wipe them with a soft cloth. Enjoy playing with your medal set!
