The Polish winery Casa Mariol found a void in the world of business agreements, they believed that such agreements needed more than just ink. What to do, well you fill pens with wine of course, and not just any wine, it was filled with their finest Cabernet Sauvignon and sent out to potential clients with a pre-order form that you could use the wine filled fountain pen to fill out.
The family owned winery wanted to promote their fine wine as a business gift and rather than send potential partners bottles of wine the pens were packaged and sent out. The idea is actually rather brilliant, Casa Mariol filled the pens with a special ink based wine that they believe has a special bonding agent that creates stronger business relationships and we couldn't agree more.
