JCD is a jumbo coin dropper that allows you to silently and swiftly steal a jumbo coin from the back of your waist.
Its design allows you to make jumbo coin slide out with just a light tap. All you need to do is curl 4 fingers to catch it.
Compared to putting it in your pocket, you never need to bend your elbow to reach the coin, and this makes difference.
If you are a beginner, you need JCD to assist you in practicing the routine; if you are a master in sleight of hands, you would need JCD to perfect your act.
