10\" X 4 1/2\" (measured without clamp)is this scarce big fellow that is in mint condition. Perfect lid, clamp and the sensitive lip on a Millville Atmospheric jar. Base is not embossed. Plenty of nice bubbles in the glass. Nice clear embossing. Not a dug or cleaned jar. Not certain if this is a half gallon size or perhaps a little larger.This bright big guy is certain to enhance your jar collection. Winner pays $17.45 for thelarge rate priority box and I cover for loss or damage on an immediate basis.I believe It would be risky to place it in a medium priority flat rate box....just too big. Low opening offer as usual.......sales should start off low! Thanks for looking.
