At 1 1/8" long, the fine-point tip on this marker can reach into confined spots where an ordinary pen or pencil would be tricky to use.
A rigid metal sleeve helps protect the slender tip and prevents it from marring adjacent surfaces. The sleeve can be retracted, allowing you to trim the tip if the end becomes worn. The marker also has a standard 1/4" wide chisel-point tip at the opposite end.
7" overall. Black ink.
