To use this set, just take out the Dopant Memories and start playing as if you're in the Fuuto PI anime world. The stickers can be easily applied to your clothes or body to create the look of using a Memory. When it comes to maintenance, keep the Memories away from water and extreme heat to prevent damage to the paint and details. If you have any stickers left over, store them in a cool, dry place. Also, be careful when handling the Memories to avoid breaking the switch. Have fun with your set!
