Pens are pretty easy to make once you have the right equipment and materials, and a little bit of patience. In total time it takes about 30 minutes to make a pen but that time is spent over a day or more depending. Maybe I'll do a tutorial on how I create a pen.
These pens are "Slimline Fancy" style and there are many other styles available. Within that style structure there are about 13 different kinds of pen finishes with gold and chrome being the most common. They are "twist" type pens where you twist the top half of the pen to make the point come out of the bottom.
