This is a Slimline Pro Gel model in 24k gold finish with a body cut from a nice piece of buckeye burl wood that has been accented with brown and white trim to give it that custom pen look. This pen is a slightly beefy version of the Slimline pen. It has a click mechanism that uses a Parker style gel rollerball refill. This pen measures approximately 7/16" x 5 1/2" long. Pen comes with a grey felt lined gift case.
