Interlocking pens, pencils and giant eraser.   Preparing you with the astronaut's essentials for school. Consisting of a spaceship eraser, two pencils, a four color pen, and a countdown 15cm ruler, means this set will get you ready for any sort of academic mission. The pen and pencils dock neatly into the eraser allowing you to easily pack up and fly around. A space saving design by Nick Lerwill for SUCK UK.
