This is a butt box compatible with Rod.com (Daiko)'s Kue rods, including the Gajo Kue and Full Field Kue. Manufacturer: FMW Material: Super Duralumin ■About the Material Made of super duralumin, a lightweight, high-strength material also used in aircraft. Its specific gravity is only 2.8g/cm3, less than half that of stainless steel (7.93g/cm3), making it lightweight. Furthermore, its tensile strength is approximately 570N/mm2, which is higher than stainless steel's approximately 520N/mm2. Each piece is produced by machining from the raw material, which inevitably increases the cost, but the absence of welds reduces the risk of breakage. → #Other FMW products are here 【Ishidai, Ara, Kue fishing, bottom fishing, piton, ishitsuki BOX, rod holder】
