NOTE: The arms and antenna were too small to build, believe me I tried, so what I ended up having to do was make a simple 2d version of said pieces. all you do is cut out the arms and antenna, fold the symmetrical pieces in half, and glue back to back. For the antenna, I made a small slit in the top of the head and stuck it in slightly (using glue on the end). For the arms, I didn't make any cuts, just put a dab of glue in the square cut-out joint (at the shoulder) and stuck it on, and held it for a few seconds.
There are no instructions, but the pepakura model file (PDO) is included (see the description). Read the pepakura section of this to see how to use it: [link]
