“Screwed Coin Box” is the only coin box where the lid can be screwed onto the box. This dramatically amplifies the impossibility of the entire effect.
You can let your participant screw the lid on themselves, yet you’ll still be able to open secretly and quickly transfer the coins inside and outside the box. The box is also examinable.
“Screwed Coin Box” also has a special “lifting handle” that facilitates unique techniques.
Use the “Screwed Coin Box” for all your favorite Boston Box effects, as well as other one-of-a-kind effects.
