This thing LOOKS AMAZING, and while handling this prop requires some effort, the result is clearly displayed in the video demo. A blue backed Bicycle card VISIBLY turns red (or a red card visibly turns blue). This effect is not easily mastered...in fact, I doubt you will EVER get it to look as good as it does in the video demo (unless, of course, you are doing it as your own video demo to post on social media). Still, the thing is just so cool you will LOVE to play with it...the gimmick will entertain YOU for hours!
