Pro Glow. You can purchase it at Sportco in Fife. As Bob said, ease of use for a consistant quality egg. Freeze appox 1# of eggs in a gallon freezer bag with the excess juice left in and they will keep for several years without freezer burn. Thaw them out and drain the excess juice. Roll them up in paper towels and stick them in the fridge for a few days to firm up. Refreeze several times without loss in quality if kept layered in paper towels.
