Using this CSM Core Medal set is easy. First, take the included Rhino, Gorilla, and Elephant medals and combine them with the medals that come with your CSM OOO Driver (or Complete Set) Ver 10th. This will give you the 10 beginning core medals from 800 years ago. Make sure to use these medals with CSM OOO drivers released in 2018 or the more recent Ver 10th for the best results. When handling the medals, be gentle to avoid any damage. Store them in a dry and cool place to keep them in good condition. And don't forget, you get free shipping within the USA, so enjoy your new collectible!
