You can watch each video on YouTube from the following links: https://youtu.be/IzMeM3jbKMg?si=mbj-4uZ9N2RPDBOW https://www.youtube.com/watch?v=Fy9R9mgLEw4 The following is a partial quote from the shop's description: This PORTAL is the ultimate sign coin transposition phenomenon, developed by Eric Chien, FISM Grand Prix champion and champion of the TV show Asia's Got Talent (AGT), and TCC, over 16 months, including three redesigns and dozens of tests and improvements. The material used for the surface of the mat is the same material that Erick actually used in FISM and AGT. Regarding operating noise, the gimmick makes a few sounds that are noticeable at close-up distances when it operates. When performing close-up performances like the demo video, you may need to use ingenuity, such as playing background music and vanishing the coin in time with the music's climax. Included items: Close-up pad x 1 Remote control x 1 Charging cable x 1 Glass (large) x 1 Glass (small) x 1 Instruction DVD with Japanese subtitles (includes an additional manual adjusted by GIN) * There may be deformation (scratches) on the product or the corners of the outer box. There is no problem with the product itself, but please refrain from purchasing if you are concerned about this. * The secret of the magic has value, so returns are not accepted if it is different from what you expected.
