Let's face it, sometimes we just buy the pen for the nib. Our Parker Sonnet is a hearty and loyal daily writer, but it has a ton of deep scratches and is even missing some of its finish on the tail of the pen. Click the headline for close-ups. Its brass-barrel construction makes it far more durable than other preowned luxury pens. The real treasure of this pen is its bouncy, fine-point 18k gold nib. It doesn't qualify as a true semi-flex nib, but it does have some nice bounce to it. Also included is a Parker converter. This pen also takes Parker cartridges. 13.3cm capped.
