Hello, These pens are turned right here in my shop. They vary from just wood, to just resin, to a hybrid of both. There are twist pens, ink well pens, rollerball pens and a few click pens.  I do design them to be as unique as the person that uses them. All of my pens can have the ink cartridge replaced when they run out, so you can use them for a long time. If you like something, I can also turn a letter opener to go with the pan and make a nice gift set. As awlays, thanks for looking!
