Rubbermaid 5QT Red Cooler for Picnics & Camping

I use insulin pens and they come 5 to a box. Well when this small chest was in the back of the car by my suitcase it wasn't even it the sun and I lost 2 pens because they got too hot. I had to change my response as to if this would work. Not that well, as you can't set the pens right on the ice and I had to place them in a container to keep them dry and from freezing. I don't think I will use it again unless I have a really big cooler and can place this one inside it to try.
