DISONCARE Medicine Cooler Insulin Cool Bag Portable Refrigerator Cooler Box Diabetes Pen Cold Cooler Mini Fridge Blue

I bought this cooler in time for summer to make sure my sons insulin pens stay cool in this heat. I live in Texas, and have gone to theme parks, hiking, parks, etc in 90 degree weather and this cooler has stayed cold the whole time even continuing onto the next day. It’s nice and fits perfectly in my sons diabetic backpack.
