The LAMY swift is a retractable rollerball pen which pairs great functionality with innovative design. They're fitted with LAMY's ever popular M66 rollerball pen refill in blue with a broad tip which ensures a smooth writing experience while the all metal barrel features a grip section has holes cut out making it easier to hold and more comfortable over long periods. Most rollerball pens come with a cap to ensure the tip does not dry out but the LAMY swift is designed with a push-button mechanism which when retracted, will keep your pen safe and ready to write with. The push-button also controls the pocket clip which is designed to retract into the body, lying perfectly flush with the metal barrel when the tip is extended to give more comfort while writing. When the nib is retracted, the clip will extend again, perfectly pocket safe. The refill will need to be fitted for this mechanism to operate correctly.
