The Character Lapel Pins are pins that were sold in the Nintendo World Store and the Nintendo "Fun & Games" Employee Store. They were only sold in the United States, and 4 were given away as promotional items. There are 12 of them, and each one is a Nintendo character. Nintendo began selling them in April 2004, and stopped in November 2007. They are 1/2 to 2 inches per side.
Nintendo is recalling the lapel pins because a there is lot of lead in them. They are asking that fans call a phone number to send the lead pins back to them. The fans that call will get a replacement pin with no lead in it.
