Actresses Mary-Kate and Ashley Olsen, right, signed copies of their new book, “Influences” at a Barnes & Noble store in New York.  The famous twins remind me that Sharpie offers its own Twin-Tip markers.  Sharpie Super Twin Tip features a Fine tip on one end, a Chisel tip on the other.  The regular Twin Tip has a Fine and Ultra-Fine tip.   Twice the Sharpie fun!
