Description The Sheaffer Prelude fountain pen in Cobalt Blue features a glossy blue lacquer over brass barrel and cap, accented by rose-gold plated trim. The snap cap securely closes the pen, and it posts securely on the barrel when writing. The cigar shaped design and mid-range length and girth of the Sheaffer Prelude model makes this a universally comfortable pen in the hand. The Sheaffer steel nib is a smooth writer, and the pen fills by using Sheaffer proprietary cartridges or the included Sheaffer converter.
