Send your own secret messages with this ingenious kit.
Contains two invisible ink pens with caps that - at the press of a button - emit powerful 'blacklight' beams to reveal the secret writing.
Not suitable for under 3s due to small parts. Invisible ink is non-toxic. UV light should not be shone directly into the eyes.
