Work to free the TARDIS with this Trans Temporal Sonic Screwdriver! It comes in four pieces which are assembled by twisting them together. The included instructions give the specific order of assembly. The Sonic Screwdriver requires three non-rechargeable LR44/AG13/A76/L1154 alkaline batteries. Demo batteries are included, but you'll need to buy more. Once assembled the screwdriver lights and makes 8 different sound effects when the trigger button is pushed and held down. Can you free the TARDIS before time runs out?
