Review on PPFISH Air Tight Accessory Waterproof Container by Charles Barney

I use these containers to take my eye drops and some medication to work, long hikes and mountain biking. They fit in the middle of a full 40L backpack and are in perfect condition after months of heavy use. You have to remember that I've had several serious falls where my backpack cushioned the impact. It's amazing what you can get for $11. These are 3 super tough, high quality, fully waterproof, multi-purpose mini containers. In addition, their size is exactly the same as the description.
