Review on 📦 5-Pack ABC Insulated Box Liners 8x8x8 - Lightweight, Durable, and Flexible Shipping Boxes for Frozen Food - Cold Shipping Boxes for Perishables by Mike Wallace

The shape and size were weird, but I was able to solve this problem by using two pockets for my belongings. What I found unacceptable was the instant transfer of temperature from the items inside the pockets to the outside of the pocket. So I put the things in double bags. Another transfer of temperature through the heater. Then he added insulation to the walls of the box. I doubt my efforts have helped. And I just hope the fast delivery doesn't spoil the food. Next time I'll buy a soft insulated fridge like insulated lunch bag for kids. Can work better and can't work less effectively. I can't imagine what the true or original purpose of these bags was or is.
