I have 2 wooden humi's and 1 cooler for NC's (which hides in a closet).
IMO, a vino or cooler sitting in the family or dinning room would never fly. Different strokes for different folks.
As for the plastic liner for sealing.... Wood works just great. Most wooden humis are laquered and sealed on the outside for looks. That outer coating is a great sealant for keeping in humidity and the inner cedar wicks moisture/adds aroma. My
Wooden humis will never fade like stone wash jeans.
