I bought a Mont Blanc Rollerball on eBay about a year ago. When it rolled off my desk and the barrell broke I sent it off to MB for repair. It's a fake! I'm very disappointed. The seller is no longer registered. On checking this site, I learned that there are ways to check for fakes MBs. Wish I'd known. This is a heads up to anyone thinking of buying a MB - do a search on the eBay Forum before you buy, just to be sure.
