An empty full of empties.

I hate Scotch whiskey, so when my parents got me this 12 year old bottle when they were in Scotland, oh, at least 15 years ago, it took another 12 years to polish it off. Now it’s full of empty ink cartridges from my trusty Tombow Zoom pen. How many cartridges did it take to fill it up? Closest guess will win a variety pack of letterpress-printed holiday cards. Email your guess to 12acrestudio@gmail.com and if you win we’ll get your mailing address and send you the prize. Deadline: noon on Friday, December 3. Good luck!
