The Retro 1951 Smithsonian Corona Rollerball is the first of Retro's Smithsonian Collection. With Retro's patented twist action top, its deeply etched barrel is reminiscent of the ornamental bronze-colored metal lattice that covers the outside of the National Museum of African American History and Culture building in Washington D.C.. Numbered and accented with matte black nickel, the top disc displays the Smithsonian logo. Homage is paid to the intricate ironwork crafted by enslaved African Americans in Louisiana, South Carolina and throughout by the lead designer David Adjaye.
Packaged in a commemorative tube which can also be used a pen stand, this pen makes great for everyday use, a gift or a collector's piece. 
 
Refill: Retro Short Capless and any Parker style ballpoint/gel refill. 
 
A little extra information:
The National Museum of African American History and Culture is the only national museum devoted exclusively to the documentation of African American life, history, and culture. A portion of the proceeds from the sale of this pen will support and further the Museum’s educational mission on what it means to be an American, and to share how American values like resiliency, optimism, and spirituality are reflected in African American history and culture.
