Our sturdy cardboard shipping boxes contain a heavy-duty polystyrene cooler with a 1 1/2″ wall thickness that contributes to insulating products from heat outside. The beef is shipped frozen and combined with one to three Nordic NI24 24 oz. gel ice packs, depending on the quantity and duration of your order. If you’re shipping distance takes longer than normal, we will pack with dry ice. Our goal is to get the product to you frozen and/or at safe temperatures.
