Quickly and easily store bird seed, dog food or any other item in a snap with this Gamma Seal Lid. Simply snap the lid onto a standard bucket (not included) and you've created an airtight, waterproof, portable storage unit. No longer are you forced to break nails and hurt your fingers trying to unsnap the lid every time you need to get to the contents of the bucket. The center of the Lid screws off, once the lid has been snapped on a bucket, for ease of access and to ensure a tight fit. The two piece design keeps the contents fresh and ready to use at short notice.
