Keep the magic of Christmas alive with this personalised Elf Surveillance letter, a playful way to remind children that someone special is watching their good behaviour. Add a child's name of up to twelve characters, then the sender's name of up to twenty-five characters; the sender appears woven through the body of the letter rather than signed at the foot, as in I have completed my mission with the assistance of Auntie Nicole. Your wording prints just as requested, though it is best to avoid block capitals so the message stays easy to read.

Measuring 21 x 29.5 x 0.2cm, the letter arrives tucked inside a plain white envelope within a brown outer envelope, ready to slip under the door or pop on a pillow. It makes a charming festive surprise for little ones counting down the days, and our great-value Christmas letters include free standard UK delivery.
