Can anyone point me in the right direction? I have seen so many of these things but never quite paid attention as I didn’t think I would need one. Now I’m going to be travelling in a couple of weeks so would like a case that has a thing to keep the pen cool. I will be using it the day after I travel and it’s the last dose so I don’t need to worry about keeping it cooled further than 24-36 ish hours. I am going to a hot country though so definitely want the cool aspect.
