This is a gently used Karas Kustoms Retrakt.  The pen is in great condition.  It is a fantastic pen that is perfectly weighted.  It has one small scratch that likely can be buffed out.  It looks exaggerated because the area surrounding it got polished from the pen rubbing against my cloth pen case.   Below is a description from Jet Pen's website:

Give your favorite gel, ballpoint, or rollerball refill a shiny new home in this unique, high-quality metal pen body, designed and machined by Karas Kustoms right here in the USA. The all-metal click mechanism is smooth and silent, and the stainless steel clip is strong enough to withstand a lifetime of use.

Two black Pilot G-2 ink refills will be included, and the pen is compatible with the wide range of refills listed under Recommended Refills/Parts. The pen also comes with springs and a spacer for use with the different refills, as well as a length of plastic tubing that can be used to make custom length spacers for other refills not normally compatible with the pen.

This pen is machined from solid brass. Its raw finish can be polished to stay shiny or allowed to age and develop a unique and hard-earned patina.

This pen has a noticeable metallic scent that can transfer to the user's hand for a short time after use.
