Mario Kart Super Circuit Button Pin Employee Promo Promotional Nintendo 2001. Pin has a scratch and some light wear on the front. The light used to blink when I first got it but now it doesn't, probably needs a new battery but no guarantees on that, it's "as is". I believe this was worn by store employees to promote the game when it first launched. I've had it nearly 10 years, it's not a reproduction. Comes exactly as pictured nothing else included.
