The Eleventh Doctor's Electronic Sonic Screwdriver

NOTE: This sonic is around 15 years old and as such may require new batteries or some TLC to the electronic connections in order to be fully functional. This sonic has been opened to check the package still contains its original batteries (they come inside the packaging, not fitted inside the sonic!).
 
This is the original 2010 release of The Eleventh Doctor's Sonic Screwdriver, featuring the extending action plus light and sound effects.
