Using this set is super easy. First, take out the DX Henshin Belt Gavv. Put it on just like a normal belt. Then, when you're ready to transform, activate the belt as shown in the show. The DX Gavv Whippia can be used to enhance your play - acting. Just hold it firmly and swing it around. When it comes to the Gochizo items, they're mainly for display or pretend play. You can collect them and show them off to your friends. As for maintenance, keep the belt and weapon away from water and extreme heat. Don't drop them hard as they might break. If they get dirty, you can use a dry cloth to gently wipe them clean.
