The Trident Pen is our first roller that does not need a cap. To operate the refill just twist the finial it extends or retracks. The clip is on the tip end of the pen so you can leave the refill extended. Do not worry your refill will not dry out.
The hardware comes in two finishes either gun metal (black chrome) or Chrome.
The refill type is a short rollerball Schmidt P3127.
The rollerball is available in two colors black, blue.
