The digital temperature display gives you further peace of mind by constantly displaying the internal temperature so you can keep an eye on it at all times.

Buying Guide
If you are searching for a reliable solution to store your insulin while traveling, this buying guide will help you make the most informed decision. When selecting a travel case for your insulin pen, consider the size and capacity of the medicine cooler compared to the size and number of pens you want to travel with. Choose a case that has more than enough room for your specific brand of pen and for the number of doses you need in case you want to bring some extra doses along with you. Insulin pens vary greatly in size; for example, while the large sized Nomad cooler case by 4ALLFAMILY can fit up to seven regular-sized insulin pens, it can only fit one Emgality pen. Another critical factor to consider when selecting a medicine cooler box is the material it is made from. Choose a case that is made from waterproof material, as this will help protect the insulin from moisture and weather. You also want to ensure that the design offers quality insulation for safety and longevity. Many medicine cooler boxes feature a safety alarm in case the temperature drops too low. Next, ensure the medicine cooler box is portable enough for your needs. Some cases are designed to be more lightweight for easier travel, while others may be heavier but have more space for storing insulin pens, making them perfect for keeping at the office. Last, decide what additional features you would utilize. For instance, many insulin pen travel cases offer compartments for other medications or even USB ports for charging devices.
