Parker Sonnet Silver-plated 750 sterling gold nib. Parker The Sonnet features a silver-plated patterned body, gold-plated accessories, a 750 sterling gold nib, two cartridges, and a box. It writes beautifully and is like new; perhaps it's the first time I've ever bought one. I inked the area, it's in very good condition. Please examine the pictures carefully.
