What if your envelopes did more than hold secrets?
Utility items like the thumb tip—versatile, timeless, and indispensable—are a rarity in magic. Even rarer is a brand-new tool that truly redefines the game.
Arcane Relics, in collaboration with Joseph Daniels, proudly introduces Janus—a revolutionary system disguised as an unassuming stack of envelopes.
Individually and together, these envelopes enable:
- Switching & substitutions
- Peeks & information gathering
- Pre-show & real-time methods
- Clean productions & seamless clean-up
Born from over two decades of refinement, Janus isn’t a single method, but a symphony of techniques. Until now, these secrets remained handmade and underground—but today, advanced production lets them shine.
Janus is a non-electronic, non-magnetic marvel that replaces clunky tech and unreliable apps with pure ingenuity. No batteries. No waiting. Just results—anytime, anywhere.
Each set includes precision-crafted props, ready to perform right out of the box. But that’s just the beginning.
Purchasers gain exclusive access to the Janus Community—a private online forum where performers and creators worldwide share routines, brainstorm innovations, and push the boundaries of mentalism together.
Welcome to Janus. Welcome to the future of utility magic.
Currently the Janus system comes in two sizes a 4″ * 6″ and a 2.5″ * 3.5″ size.
Currently we have three colors for the envelopes Brown, Lilac Purple, Midnight Black.
All Janus envelopes are 80lb paper.
