Sarah, Duchess of York has released 1 fountain pen model in 3 colours (blue, yellow, orange) with Montegrappa.
It's a limited edition and only 100 pens are available of each colour.
From the website:
"Duchess of York - Visions of Nature
Brilliant colours and joyous detailing evoke the natural kingdoms of Ocean, Forest and Garden. In these places of solace and inspiration, beauty lies idly… awaiting discovery. Writer and humanitarian, Sarah, Duchess of York, reflects on nature’s wonders in a rare collaboration. Pretty, sterling silver friezes fuse with effervescent celluloid in a silhouette abundant with lively, feminine charm."
Nib sizes: EF F M B BB STI
18k nib, 925 sterling silver trim, celluloid, piston filler, fairly heavy at 66g.
Looks actually nice, especially for Montegrappa (some of the pens they've released are not very... pretty...).
