Plate Topper was voted a top ten finalist in Walmart's Get on the Shelf crowdsourcing contest! There were over 4,000 entries and the public cast over 1.1 million votes.

PlateTopper, based in San Francisco, enables people quickly and easily to store food right on their dinner plates with a plastic topper. "All you do is press down on your food" on a plate, "and you have this airtight seal," founder Michael Tseng explained in a video. The product is now available on for $19.77.
