These are new and have the breakable seals in place. This creates a spill proof seal. To remove you need to break or cut at each opening around the lid. Once cut you can reuse the lid and still have a tight air seal its just not as secure if the container is dropped or thrown about.
Hard air tight lids for plastic containers.
We can drill the hole for an airlock (sold separately)
note: Home Depot, Lowes, etc sell these for about $2.00 
We also have the Gamma Seal Lids which form an air-tight waterproof seal with a screw on top.
