I have to take a lot of pills. I was able to avoid that all of my life and then, suddenly, I got old. It happens. I wouldn't recommend it. Anyway, I experimented with different pill cases and containers for those pills I have to take with me when I'm at work or out of the house. they all KIND of worked, but they were either bulky in my pocket, or were pendants around my neck that didn't hold everything, etc. My biggest problem was that they were a bit loose, so some of the pills got knocked around a bit and suffered slight damage. Not good. I then tried these bags and they are perfect. Fit exactly the pills I need to take with me and they are sort of streamlined, so there is no rigidity and the pills travel great without adding bulk. They zip to create a tight seal. I realize that this is a long review for some small plastic bags but they work great and the quantity (at a very cheap price) means I'll never run out.
