Well, the original hard okie was made by Maxwell (Grizzly) and Luhr Jensen had their Egg Drifter which was knockoff (but almost identicle). Then, not sure if LJ bought the rights, or what happened. But then LJ made the hard okies. Then, to lower costs I assume, they went to the foam injected okies. I still have okies made by Grizzly in the original package, and the egg drifters in original packages. Then, have some of the hard "LJ Okies" in packages. Miss the old ones. Just too labor intensive to produce.
