Finishing up the writing for my first homebrew and will soon need to make:
a) some invisible ink 'moonlight runes' (or whatever) on letters/ maps
b) wax seals for letters
Any product recommendations from Amazon or another online retailer that you thought worked well, or was easy to use/ work with?
Edit: For the invisible ink, I'm thinking of the kind that shines under a black light. I've seen the egg white and lemon tricks but I need the messages to last longer and be a bit more robust.
For the Wax seals I found these recently. I hope this helps you.

A simple black light pen will work for invisible moon runes! Check amazon, they should be really cheap.
