Did anyone track their response cards with a black light pen? If so where did you get it?
I just used a regular pen and wrote really small in the corner. No one has said anything about it. It's a good idea though cause some of them come back only half filled out so at least you know who it's from.
I ordered them through Amazon and I love the idea of them being numbered without my guest noticing. I got 4 for about $3.00. It really came in handy this weekend when I received a RSVP with just a last name. Luckly it was numbered because I sent out 3 invitations with the same last name.
The name of the company on Amazon is Invisible Pen and it's $2.70 plus free shipping. Good luck.
I got mine from Amazon, too! Super cheap and seem to work well.
