The Blackwing pencil was introduced in the 1930′s by Eberhard Faber and was the pencil of choice for Oscar, Grammy, and Pulitzer Prize winners throughout the 20th century. After it was discontinued in the 1990′s, fans began paying as much as $40 per pencil to seize unused stock. In 2010, Palomino revived the Blackwing, and it is now available in three different models.ExpirationThis product has no expiration date or the manufacturer has not provided an expiration date.
