The LAMY dialog 3 Fountain Pen – Piano Whiteis a pioneering cap-less fountain pen. Due to its fascinating rotating mechanism, the spring slides effortlessly out of the interior of the barrel, while the clip lowers. While the Dialog 3 is closed, a ball valve automatically pushes in front of the opening, eliminating contamination and the nib drying out. The ingenious design of the clip allows the user know if the nib is still retracted because the clip has recessed and will not attach to the pocket. The LAMY dialog 3 Fountain Pen is available in three other styles: Black, Palladium, and Piano Black Available Gold 14K Nib Sizes:Extra Fine | Fine | Medium | Broad | Oblique Medium* | Oblique Broad* *Oblique Medium and ObliqueBroad are available by special order with extended delivery time.
