The Gamma Seal lid is a unique solution to the exasperating finger-nail breaking lids of yesteryear. A pail without a lid is only so useful... while a pail with a Gamma Seal lid can be used limitlessly! The Gama Seal lid is not only re-sealable, but the heavy duty construction allows it to be reusable. Easily RE-SEALS your pail! or Transforms your clean pail into an airtight STORAGE CONTAINER! Over 150 million 5-gallon pails are manufactured each year. Millions are discarded due to the absence of an easy re-sealing lid. The Gamma Seal lid transforms most 12" diameter plastic pails into leak proof, airtight storage containers that protect the contents from exposure to the environment.
