METAL BUILD（メタルビルド） is the flagship line of TAMASHII NATIONS, the high-end brand of BANDAI SPIRITS. Each figure combines a die-cast metal frame with precision paintwork, turning Gundam mobile suits into collector-grade pieces that are complete right out of the box. Most releases are sold through Tamashii Web pre-orders or lottery sales only, so they rarely reach regular retail. For overseas fans a Japan proxy shopping service is the most direct way to get them.
