Crafted from shakudo migaki-ji (polished shakudo), the set depicts bats flying under a full moon, with the bats rendered in suaka (unalloyed copper) with intricate high-relief carving and subtle gold inlay for the eyes. The piece is accompanied by an NBTHK Tokubetsu Hozon Tosogu certificate issued in Reiwa 7 (2025).
