WOW I SO wish I had this diary as a kid! It’s an Invisible Ink Diary (Merlin) that comes with a special pen – and you can only read the message with the special decoder light! I’m not sure how hard it would be to read if you can’t see it but the reviews are great and this looks SO cool for your super secretive kid!
They seem to run about $10-$11 each for the Merlin Wizard and the Castle Invisible Diary. The Fairy Diary and Dancer Diary are almost $19 each.
