Yes, these are cufflinks made from actual balls used during the 2010 World Series (And now, the 2012 World Series. Choose your year in the drop-down!), when the San Francisco Giants defeated Texas Rangers to win their first title in San Francisco and the Giants' first in 56 years. Since the G-Men won in only five games, Tokens & Icons has only been able to secure a limited number of MLB Authenticated game used balls from which to make these links. When they're gone, they're gone, so get 'em while they last. And really, what better way to celebrate the victory than to have a literal piece of the action?
Each individual cuff link is affixed with an unique MLB Authentication hologram that can be referenced at MLB.com for game details. Every pair of cuff links is also attractively gift boxed and comes with an individually numbered story card.
