Getting your hands on these exclusive pens isn't very difficult.
If the product is not available at the store, buyers can log on to www.williampenn.net and place an enquiry.
The Gitanjali Group also stocks the same at its retail jewellery stores across the country.
The names of Indian buyers of these pens are not divulged as they are "highly private people", says Anita Paily from William Penn.
Stores also pull out all stops to woo such buyers.
William Penn, for instance, offers private screening to customers who wish to see the product at their convenience.
The buyer then becomes part of a "platinum class" and enjoys the benefits offered therein (speedy delivery, priority in case of "limited edition" merchandise).
On request, the buyer's name can be engraved on the pen too.
