case

I recently changed my insulin from Levimir to Tresiba and have been annoyed that my fast-acting insulin case is the same as my long-term one. I see this as an opportunity to get a pen that I can design with something I like, but I can't find anything, does this sort of thing exist?

Hi everyone, I am looking for some advice on carry cases. I am looking for one small one that can fit in my pocket, which has room for pens, rubbish etc I am also looking for an all in once case for holidays that can store anything and everything (cold packs etc)
