Premium Bandai has updated with a preorder page for the Complete Selection Modification Hopper Zecter. While the belt itself is specially marketed for the Hopper Zecter, it can also be used as a belt for the other riders sans Kabuto and Gatack since they also used the same belt.
The Hopper Zecter will feature various phrases from both Sou Yaguruma (Kick Hopper) and Shun Kageyama (Punch Hopper), which can be previewed on the official preorder page. Preorders will open later today and will close on May 8 at 11 P.M. JPST. The item will be released this July priced at 12,960 yen.
Those who are interested should contact their preferred middleman for more details.
