Black Hole

May contain traces of nut
I had one of those multi-coloured biros as a kid too.
It was a bit of a nuisance to retract the colour and select a new one every time. And it was hard to write with as the body was so fat.
The one I had (with about a dozen colours) didn't retract at all - you had to unscrew the top and swap refills by hand.
