I bring up the subject of recycling Korbel boxes each year around New Year's as this is the time of year when Korbel boxes are available in quantity from liquor stores.

I am posting the following photo story to show how to ideally resize them for the purpose of storing insulators.

This picture shows an already completed box next to the one I am working on. I cut the seams down to a height of 5 1/4" which lines up with the height of the dividers.
