The BLACK MARIAH Masterclass is available to watch for FREE HERE
The BLACK MARIAH is a Precision Modification Device that allows you to modify any playing card/s in the deck so that you can instantly cut to that card without having to know where the card is.
The BLACK MARIAH Device allows you to remove an extra 1mm from the corner of any playing card/s - changing the standard 3mm corner to a secret 4mm rounded corner - this modification cannot be seen by the naked eye of a participant or discovered under inspection or on accident, yet the trained eye can not only see The BLACK Mariah playing card, but also feel it’s position and cut to it naturally with minimum effort without looking.
The BLACK Mariah Device is known as a ‘Corner Rounder / Cutter.’ It is a tool of deception that has been updated / modified to include a much sharper and precise blade… Where I got these devices, I took them to a blacksmith who helped me take each device apart, sharpen and smoothen the blade before reconstructing to create this precision device.
