One of a great number of semi-cottage industry pen-makers in India, Guider is in many ways a throwback, which I mean that in the most complimentary way. The workshop in which they are made is rigged very much in the mode of pen-makers of the early 20th century, with the reliance resting upon the skills of the craftsmen rather than upon the modernity of the tools. The only source for this maker I know of in North America appears to be removing Guider from their inventory. The model names, by the way, are the invention of that importer, rather than the company itself, and are thus unofficial.
Something I found very appealing about this makers pens is the clips, because if this pen had been made sixty years earlier it could be accused of copying the highly distinctive clip of the Parker line of the 1940s. I prefer to think of it as an homage.
