This is a series of gashapon (capsule toys) or trading figures depicting prop airplanes.
Here's a collectible series of "special attack" aircraft, boats, submarines, and related weapons, such as the Kikka, Tsurugi, Ohka, Kaiten, and Shinyou. "Special attack" usually means "suicide attack," and such craft as the Ohka and Tsurugi were purpose-built Kamikaze aircraft. The Kikka jet was only designated a "special attacker" right at war's end, but never saw service due to the cessation of hostilities. The eight types in this series' lineup are illustrated below, and there's also a "secret item," for a grand total of nine types to trade and collect. Sold by the randomly-packed box of 10. Please note that these are trading items and are individually sealed and randomly packed in boxes of 10 before shipment to HobbyLink Japan. As a result we are unable to honor requests for individual or specific items, nor can we promise you which one(s) you will receive in a box. Please order only if you are willing to accept any of the possible types.
