Montblanc continues to produce rollerballs; contrary statements from specialist trade are incorrect. An official end-customer-accessible serial-number database for authenticity check does not exist. On the Bohème, the Pix imprint under the clip is to be expected, and on fountainpen.de under the PDF boheme-vergleich.pdf typical counterfeit features for model comparison can be found. Online sales by authorised Montblanc dealers are forbidden; therefore eBay bargains under dealer purchase price are critical; suspicious are short eBay lifespan, few ratings and unusual purchase handling. PayPal protection is limited and only effective up to a maximum of 500 euros, possibly with additional own contribution; on more expensive pieces the damage in counterfeit case is mostly only partially covered.
