THE WATERMARK CODEX
15 Euro

THE BLURB:
Imagine if you could mark envelopes in any way you need
(numbers, letters, marks) for your particular invented
trick. The marks are invisible to all except you,when you
innocently 'activate' the marks. You have just imagined THE
WATERMARK CODEX. No chemicals, no gadgets, no UV Lights, no
hassles or troubles.
