Hand this pen to your favorite musician, sport, or movie star for signing autographs, photographs or memorabilia. The dual point multipurpose marker leaves a permanent mark on most non-porous surfaces. One end is for details, with an extra fine plastic point that won't break down. The opposite end is for broader lines, with a tough fiber point built for heavy use. The ink is resistant to water. Pick from eight colors to coordinate with that special memento that needs an ID.
