Okay, maybe it's a silly name, but the PopSome containers are really handy. They employ the patented Oxiloc system that creates an airtight seal with a simple push on the lid. See that spout sticking up in the lid? Just push down on it to seal the container. Then, simply pull it iup to open and create a pouring spout for the contents. The various sizes are great for airtight storage of spices, rice, flour, nuts, candy and more.
