Using your SG BoonBoom Vehicle Set is easy! Just take out the vehicles from the set and start playing. You can use them on their own or connect them with the DX BoonBoom Changer if you have one. When passing the vehicles through the Boonboom Trailer, remember they won't transform. As for maintenance, keep the vehicles clean by using a dry cloth. Store them in a cool and dry place to avoid any damage. Have fun playing with your SG BoonBoom vehicles!
