insulated shipping box large size 16x7.5x11" foam Aluminum foil box X 5packs, Thermo Chill Insulated delivery mail mailing carton for fresh, frozen sea food, milk, meat. (16x7.5x11" X-large)

Great product for shipping baked goods to my grandchildren.

I received already open package(more like return package) . Received 4boxes instead of 5 boxes.. otherwise boxes are sturdy and value for money.

The cardboard is very sturdy, but the insulation is very mild.

The corners, where attached didn’t appear strong, but it worked to ship across the country.

It’s my fault for not paying attention to the dimensions. They were really thick and sturdy, just a little smaller than I was expecting. But again, my fault.

The shipping boxes are very nice and Leak proof. But the size is little small. The price for the boxes are too expensive 😞😞
