You'll receive three beer caps along with the simple gimmick. You can use your own bottle caps if you prefer - any caps will work with the gimmick.
Clink Caps works great with a glass or a coffee cup because your audience will hear the caps arrive even if the cup isn't clear.
John teaches everything. Alternate handlings are taught such as covering the glass or cup with your cell phone or a deck of cards while the caps arrive. Enjoy!
