I use these boxes every year to ship my game meat from Montana to Massachusetts via UPS 3-day, at 50 lbs. meat per box, and last week 8 boxes were shipped from MT Tues. and arrived in MA Fri. with the venison still between 19°F. and 23°F. Next year I will ship the empty boxes back to MT to do it again. I usually get 4 or 5 seasons out of each box before seeing the need to replace any of them. Very good and solid. Does the job nicely.</p>
