The Rockster is my signature pen. It is a TroubleShooter 1313 model made from Black Tortoise Cellulose Acetate, making it feel warm and soft to the touch in the way only cellulose based resins can.
It comes with a Bock No6 black nib and has a Rockster red accent ring at the grip. The pen is finished with my sterling silver logo coin, made from 100% recycled silver.
The 1313 is a medium sized pen with no step between the 13mm cap threads and the remainder of the barrel. The grip section is slightly pinched to ≈12mm diameter at its narrowest point. As these pens are all hand made there may be small variations on measurements.
Length - Capped ≈ 139mm, uncapped ≈ 134mm
It is provided with a high quality Beaufort Ink international standard sized converter. Standard ink cartridges can also be used.
