The Pica-Ink indelible pen has a long, slender tip to reach into confined spots where an ordinary marker would be tricky to use. It has a convenient holster with a toothed clip that grips a belt firmly, making it easy to withdraw the pen one-handed, and features a tough, oversized plastic housing that is easy to grip, even when wearing work gloves. A rigid metal sleeve helps protect the tip and prevents it from marring adjacent surfaces. The sleeve can be retracted, allowing the tip to be trimmed if the end becomes worn. Available in three colors, the pen gives a 1mm line (though generally indelible, it can be removed with alcohol). Made in Germany.
