Let the world’s most famous British police call box help you read at night with the Doctor Who TARDIS Book Light. But just like the Doctor, this light has more tricks up it’s sleeve- it comes with a UV pen:

Write a secret note- the pen’s writing can only be seen under the soft blue light of the Tardis booklight. Great for people who like to take notes in their books but don’t like any visible marks in them. It has a clip on the bottom and an adjustable neck so it can be used beyond just books.
