Best For RSVP: DLUCKY Spy Ink

Buy on Amazon

The dlucky spy ink should be able to handle its purpose and duties with ease. It is a great way to get them to write. The lights aren’t super bright, but definitely bright enough. They are awesome for the fact that there is a built in light so that your writing isn’t sloppy under the real black light. The caps each have a light in them with a paper tab to remove when it is time to use one. The top has a little light in it so if you press a button on the side, the light goes on. It allows you to see a little of what you are writing.

It’s easiest to read the secret messages if you hold the light back a little bit of what you are writing. They will make excellent birthday gift bag goodies as well.
