The style is called Slimline Pen and it is about 5 inches long (13cm). The wooden pens are slightly heavier than regular ballpoints.
The mechanism features a satin gold finish and it has a twist style opening. It takes Cross style ballpoint refills which you can buy at most office supply stores. You simply pull the pen in the middle to open and refill when the time comes.
Each pen will come in a clear plastic protective case.
