MD Mini is perfect for those off-the-cuff situations: take it off your keychain, blow their minds, and clip it back on – it’s as impactful in casual settings as it is during a formal performance. And, with the look and feel of an ordinary Rubik’s keychain, it won’t only look like it belongs on your keys; it’ll never leave them. MD Mini is great for mind-reading effects, color readings, and more.
