I used to collect Zippos back in the day, like 20 years back. I've about 30 of them, the best being my micky mouse one:)
Doing a yearly zippo as an overall process would be easier compared to vodka but i think people would be more likely to buy HIVE vodka. I could be wrong. And FYI, i'd buy a HIVE zippo each year if one were created :)
