Manufactured by Acme.
Famous for his emergency housing made from recycled cardboard, Japanese architect Ban designed this functional rollerball in 2005.
Appearing like the Japanese tokaido shinkansen (bullet train), its twist mechanism reveals the pen tip. Four different measuring scales are laser-etched onto the pen shaft, whilst the triangular shape makes for easy resting - you just need another pen to draw a straight line!
This pen is packaged in it own unique, magnetic case.
Manufactured in aluminium.
