The third part of Ultimate Guard's “Katana: The Shogun's Journey” series includes four Boulder 100+ deck boxes along with a matching Arkhive 400+ mass storage box. The four Boulders — in the designs Soushin (Blue), Kousei (Red), Kouyo (Brown), and Suirei (Green) — fit perfectly into the breathtaking wood-art inspired Arkhive 400+ (available for purchase separately).
