Experiences with Blankenhorn/fuellhalter.de are consistently positive: fast, well-packed shipping, friendly telephone and e-mail contact as well as proper service in the shop in Frankenthal too. The company is an official Montblanc dealer, so the warranty papers are delivered fully filled in. In individual cases there can be typing errors with the serial number on the warranty papers — in case of warranty it is therefore important to check the entry immediately to avoid later problems.
