The Sonic Screwdriver is a very cool Dr Who toy toy with which children can write in invisible ink which is only visible when the light from the Sonic Screwdriver is shone on it.
Kids love writing secret messages that only they can read and the Sonic Screwdriver toy comes with a booklet that has lots of Dalek/Grallifreyan symbols that the children can use. The Sonic Screwdriver uses UV light to reveal the messages that have been written and it also has some cool sound effects which make using the Sonic Screwdriver more fun.
Lots of the online toy shops sell the Sonic Screwdriver pen and we have displayed all that we could find on the right with the cheapest first so that the cheap deals are at the top of the page.
