The gimmick is definitely fragile so you do need to be very careful with it but there is enough
supplies to fix the gimmick if you break it and shows how to fix the gimmick in the explanation
video. Additionally, Avi Yap explains how to carefully handle the gimmick coin and what you should
not do that will lead to breaking the coin. Avi Yap also goes through some routines you can do with
the coin and also shows how you can perform the trick without the gimmick version if you don't want
to use the gimmick. Avi Yap is an awesome coin magician and does a great job at explaining.
