On the photos, no signs of a counterfeit are recognisable; the set appears original. The assured two-year warranty, however, is problematic, since this can actually only be granted by authorised specialist retailers, who may not sell on eBay. Such offers often come from foreclosure sales of former specialist retailers or from clearance sales of office-furnishing houses that have discontinued the writing-instrument business. A warranty via the manufacturer is in such cases not to be expected.
