Hemingway 'Between The Lines' is one of the rarest (next to the 'In Between The Lines') that the Fuentes produce.
Extremely limited in production, very few are made. They are made by only the most skilled rollers, and are put away in their aging rooms untill they have enough to box up and introduce to the public.
This is usually is done only around Thanksgiving and Christmas, and doesn't happen every year.
The MSRP on these are $13, but due to the rarity and small numbers, they sell for is what the market will bear. During lean times, they have been known to sell for up to $50 a stick.
