The Copernicus exists exclusively with mother-of-pearl star and not in green; the writing instrument in question is therefore clearly a fantasy product or counterfeit. The nib too is recognisably poorly imitated; the star is missing and the engraving does not surround the entire nib face. Suspicious eBay listings can be reported via the help form ('Counterfeits and copyright violations' > 'Trademark violation' > 'Counterfeit clothing, sunglasses and accessories'). More effective is direct reporting to Montblanc, since only the registered trademark holder can take legal action against the seller and have eBay remove the listing.
