The Pallene can be converted from a rollerball to a fountain pen and vice versa. On the rollerball the refill is replaced by unscrewing the nib assembly from the lower barrel. On the fountain pen, unscrewing the nib assembly from the lower barrel will allow access to the ink cartridge/pump.
The Pallene is offered in two configurations, postable and closed end. In the postable Pallene the cap can be threaded on the end opposite the nib during writing operations. In the closed end Pallen the cap can not be posted.
Lower barrel diameter - approx. 9/16"
Upper barrel diameter - approx. 19/32"
Overall pen length - approx. 5 1/8"
