XtremeMac has announced the availability of its Shieldz Collector Series cases for the iPod shuffle. Featuring officially licensed movie and cartoon characters and major league baseball team logos, the $20 cases protect your shuffle while personalizing it with your favorite character or team design. Eight designs are currently available: Batman, Darth Vader, Yoda, SpongeBob SquarePants (two designs), New York Yankees, Boston Red Sox, and St. Louis Cardinals.

“Shieldz Collector Series are clip-on shields made of strong, impact resistant plastic that feature full-color artwork from MLB teams, movies, and TV shows. The secure snap-on design protects the front and sides of the iPod shuffle while allowing easy play-through access to the music player’s controls and earbud jack. Furthermore, Shieldz provide additional protection against accidental loss by securing iPod shuffle to its neck lanyard or the XtremeMac SuperHook.”
