This new toy version is a faithful recreation of the current Doctor's Sonic Screwdriver, which debuted in the season nine episode "Hell Bent." This is the first Sonic Screwdriver toy to have four light modes and four sound effects. The Doctor has carried many Sonic Screwdrivers of various designs throughout his lifetimes and this second Sonic Screwdriver for the Twelfth Doctor, played by Peter Capaldi, was "gifted" to him by the TARDIS after his previous version was lost. 3.4 x 2.6 x x11 inches. Requires 3 x AG13/LR44 button cell batteries (included).
