Aluminum scale featuring the runway of Hamamatsu Air Base, 15cm. I purchased this but am selling it as I have no opportunity to use it. Each one is precisely crafted using a high-precision laser to carve the aluminum, and the markings and designs are printed, making it resistant to scratches and dirt, with a precise construction. The scale has 'cm markings' on one side, the same as a general ruler for measuring length, and '1/25000 scale markings' on the other side, which is convenient for reading maps and aeronautical charts, making it a welcome specification for aviation fans and pilots.
