RIVENDALE WRITING INSTRUMENTS: The Rivendale Rollerball is a sleeker, lightweight counterpart to our Regent Rollerball. Its sleek, understated design and spring-loaded clip make it an ideal everyday writing instrument.  The Ball Point Pen features a smooth twist action mechanism.  Both pens come in black or platinum with silver accents. We can engrave your logo and initials to make it unmistakably yours. Dimensions: .3 in. Dia. x 5.75 in.
