  • Starting Aug 29, 2025, U.S. Customs may charge duties on all imports, even under USD 800.
  • Duties (or Import Tax) are the responsibility of the buyer/importer, not CSTOYS.
  • USPS typically collects duties and fees at delivery. 
  • If the recipient refuses to pay, the parcel may be returned to Japan.
  • CSTOYS will not refund product cost or shipping fees if a parcel is returned for duty refusal.
  • Any re-shipping costs due to customs delays or returns will be borne by the customer.

Includes: 
- Cross-Z Magma Knuckle
- Dragon Magma Full Bottle

The DX Cross-Z Magma Knuckle from Kamen Rider Build is the transformation item used by Banjou Ryuga to become Kamen Rider Cross-Z Magma.

Insert the Dragon Magma Full Bottle into the Cross-Z Magma Knuckle, then attach the unit to the separately sold DX Build Driver. Turning the Build Driver lever activates the rotating gimmick, lights, and transformation sounds. Turning the lever again activates the finishing attack sound.

The Cross-Z Magma Knuckle can also be used on its own as a roleplay weapon. Pressing and releasing the button activates charge and attack sounds, giving it play value even without the DX Build Driver.

This is a strong Kamen Rider Build collectible, especially for fans completing the Cross-Z / Banjou Ryuga transformation item lineup.
