Pens: I cant really talk much bout pens, but below are a few products i have seen and used:
Gregory Wilsons Recapped: Great effect, teaches you misdirection, sleight of hand, good stuff. Can be found in Off the Cuff, On the Spot, and Back in Action 2 i think.
Appolo Robbins Son of Recapped: Similiar Effect. Requires an extra prop. But looks a lot cooler. A lot more twists. Can be found in Cultural Exchance 2.
Jesse Feinberg's Cigapen: A very visual effect. A cigarette turns into a pen with just a wave.
Jesse Feinberg's Write Angle: A pen bend, comes with gimmicks etc. Very visual effect. When presented well, will look kickass. I made a Sharpie version
Jesse Feinberg's Sharpie Manual: His manuscript on Sharpie Magic. This isnt the sleight of hand magic though. This is the gimmick he made for performing with sharpies and mini sharpies.
Perplexing Pen: Similiar to the PK Sharpie. Pen is placed on a glass. The magician concentrates, it falls off. Comes with gimmick. Can be done feet away, no thread, no wind, totally clean.
Psychokinetic Pen: Same thing as the Perplexing Pen but with a Bic brand pen. Comes with gimmicked and non gimmicked. Produced by Banachek. I like this more than Perplexing pen as this is more flexible to use.
PK Sharpie: Same as the other two pens above, but with a sharpie.
Mislead: More of a pencil trick, visual pencil through bill. Copperfield did this before. pretty nice.
John Cornelius' Bendable Pen: Basically a gimmicked pen which allows you to bend it but others cant. kinda pricey, but whatever.
Super Sharpie: Im not sure if this is the real name of it, but basically it is the same as the PK Sharpie, but you can use it on a lot more surfaces. This one can rotate then fall as well. The other 3 pens are not under your control, while this one is. Costs a lot more but yea...
