Using this product is a lot of fun. First, take out the Neo Decade Driver and the K - Touch 21 from the set. Insert the included cards from W to Zero One into the appropriate slots on the driver to activate different functions. When playing, make sure to handle the cards gently as they are delicate. Also, keep in mind that these cards might not work with previous DX releases, so don't be disappointed if that's the case. To maintain your set, store it in a dry place away from direct sunlight. You can use a soft cloth to gently clean the driver and the K - Touch 21 if they get dirty. Have a great time with your new toy!
