Regarding travelling with luggage, the recommendations are as follows:
When traveling, bring a copy of your prescription and a letter from your doctor containing detailed information about the medicine (including its generic name, not just the brand name and the name of the medical condition you need medication for). In addition to helping you avoid any problems at customs, this is very useful if you need medical help while you are out.
We use insulin pens as a standard of reference for capacity, but the version can be used for any type of medication that requires safe storage in the 35.6℉- 77℉ range.
Moreover, this version comes in 3 different beautiful colors to accommodate every taste.
Note that this model is a lightweight solution. If you are going on extended travel trips, we recommend checking our USB Powered models.
