Polar Tech 245C Thermo Chill Insulated Carton with Foam Shipper, Medium, 17" Length x 10" Width x 8-1/4" Depth, Original Version

This cooler (plus dry ice) kept breast milk frozen for 48 hours during shipment. Make sure to pack it tight! It held 50 six ounce bags with 5 sheets of dry ice. The dimensions listed at the inside dimensions. External Shipping box: approx 21x14x12.

Worked perfectly for shipping breastmilk, I was able to fit 490 oz in this size.

This was such a great idea. I shipped frozen things from the south state to HI and everything was still froze upon arrival. It was easy to use and everything for wonderfully. The foam quality was great!

Thank you Polar Tech and Amazon for making these insulated shipping boxes available! I have used them at least eight times to ship food across the state to my student. They are expensive to ship when filled, but I have learned a few things about shipping. However, now they are no longer carrying the boxes I have come accustomed to using, and they are not selling two count boxes for one price, but singular boxes for a higher price. Supply and demand is at work here, so I had to order what was available. Please notice the price increases when purchasing these boxes. I find them to be super sturdy, able to arrive in tact each time, and able to keep the food cold when the R-Brix blocks are included. Please bring back the Polar Tech 227C, 15.5"L x 13.75"W x 10.5" H, 2 count. They are well worth it!

The only thing is they parked in front of a drive way not mine but the neighbors across the street

I used this for shipping breastmilk to the baby I delivered via surrogacy. It works great and kept the milk frozen ! It is sturdy & held up to FedEx throwing it around.

This was perfect for what I needed. It provided maximum shipping capacity and was a great value for the money. The foam was an excellent quality of thickness and the container was the perfect size for storage that I needed. It was great that the shipping box was included also.

I recently traveled from Detroit to LA and needed to transport enough frozen breast milk (enough for 10 days) for my 18 month old. I was able to tightly fit about 305 oz of breastmilk in this cooler along with maybe 2-3 freezer ice/gel packs. I took this box with me and checked it in for my flight on Delta and had it come along as a "check in bag" to LA, as this option was MUCH cheaper than FedEx shipping. I was nervous about the long travel day as I did not want the milk to begin to thaw out. In total our travel time from our home to our final destination was around 16 or 17hours. We had the box in our rental car on a 70 degree day for about 6 hours of that total 16 hours. When we arrived to our destination the milk was completely frozen. It did not thaw out one bit!! One thing I would like to note is that the only down side is that this box does not have handles so it was rough to hold it and walk around the airport along with our several bags, car seat, stroller and other baby supplies. If the outer box had handles I'd say it's a perfect product! I assume there are no handles on the box due to temperature regulation of the cooler? Otherwise this was a great product and did the job for me!
