With hexagonal styling the Vertex kit is both functional and beautiful. The click pen uses a 3/8" drill bit and has a single press in cartridge that is smooth as silk. The rollerball and fountain pen versions have a convenient and stylish magnetic cap that can be used to cover the writing end, or post on the back end of the pen. The magnetic cap makes threads obsolete and increases convenience. The magnetic version uses a 10.5mm drill bit.
