A simple which hand routine that can be performed anywhere. Also includes John's impromptu versions of Which hand, Saucy Kurotsuke & the Guilty secret society.

Totally sold out at the Blackpool Magic Convention 2022

Praise for The Twins: "The Twins is a genius trick that you can carry with you all the time. No electronics, no magnet... 100% surefire! I love it!"
- Luca Volpe

"It's great! Really simple and direct. It's probably one of the most direct 'Which hand' routines I've seen. Really good thinking. Congratulations on a such a practical effect."
- Marc Paul

"A wonderful routine that, like all of John's effects, is simple to perform but baffling for the audience. Highly recommended."
- Kieron Johnson
