The Rollester Rollerball pen kit offers a large tube for adding that individual accent to this super pen
With the tube at over 80mm long this makes a substantial project and has a pen cap that posts on the heel of the pen with a good quality Taiwanese pre-installed nylon seal (some similar kits require self-installation)
Finished kit length approx 130mm
Drill size required 9.5mm
These kits offer very easy assembly
NB: Our new specification kits (Chrome models) do NOT require a spring they are designed to fit the tube length exactly with a specially shaped heel for securing the refill.
