Sebastien Calbry is a master craftsman of gimmicked playing cards.  He has collaborated with other magicians to produce effects that use gimmicked cards such as Badge, Off-Set and Manivelle.
In “Raw”, Sebastien Calbry join forces with another French magician Jordan Victoria to produce 3 gimmicked cards.  They are:
Gimmicked Card No 1 – this allows you to write or draw something on the back of a playing card.  Then, by waving the card, you can magically change the writing or drawing to a different one.  An application will be righting a wrong prediction written on the back of a playing card.
Gimmicked Card No 2 – this allows you to transform the back of a playing card.  The gimmicked is specially constructed such that it allows you to first change two-thirds of the back, and then visually changes the last one-third of the back.  An application will be to locate a selected card only to have it on a wrong colour back.  With a wave of your hand, you change the back colour to the correct one.
Gimmicked Card No 3 – this has the same function and design of gimmicked card no 2, except that it allows you to transform the face of a playing card.  Again, you can first transform two-thirds of the face and then the final one-third.  An obvious application will be righting a wrong selected card.
You receive all 3 gimmicked cards made with bicycle cards, and a password to download an instructional video.  The video is in the French language but it has English sub-titles on the appropriate segments.
The 3 gimmicked cards are very well-made.  They all work very smoothly and silently.  This is because they do not contain magnets that can make noise, or elastic threads that may break.  They are also very easy to operate.
Unfortunately, the change cannot be performed surrounded and the transformed card cannot be handed out for examination.  Nevertheless, the change is quite visual and magical.
In the final part of the video, you are taught how to construct each of the 3 gimmicked cards so that you can customized your own cards.  At this price for all 3 gimmicks, you may want to consider purchasing rather than making them.  (7/10 stars rating)
