Using the Tech Deck Versus Series 2 - Pack is super easy. First, take out the two fully assembled finger boards from the pack. You can start skating right away on the included street feature. To have some friendly competition, use the Challenge Cards. Draw a card and try to complete the finger board trick on your turn. When you want to expand your skatepark, you can buy the Big Vert Wall or Pyramid Point ramp sets separately and use them with your finger boards. As for maintenance, keep your finger boards clean. You can use a soft cloth to wipe off any dirt. Make sure to store your finger boards and Challenge Cards in a dry place to prevent damage. And remember, have fun while you're riding, flipping, and grinding!
