Using this CSM Core Medal set is easy. First, if you have the CSM OOO Driver (or Complete Set) Ver 10th, take out the medals that come with it. Then, add the 2 tiger medals, 1 lion medal, and 1 cheetah medal from this set to complete the 10 beginning core medals. You can enjoy the fun of combining different medals with your compatible CSM OOO drivers. When you're done using the medals, store them in a cool, dry place to keep them in good condition. Avoid exposing them to extreme heat or moisture, as this could damage the medals. And always handle the medals gently to prevent scratches or other damage.
