What is the origin of the 2001 BIONICLE pin? Recently I got one of these in a lot.



Picture of the back

Prior to receiving it, I didn't even know it existed, and can't find any information on it on the web.

What is the origin of this 2001 BIONICLE pin? Was it sold or handed out somewhere as a promotional item? Made for and worn by LEGO employees? How would one have obtained one in 2001 (assuming that's when it was made)?
