This is a 1/2 gallon Mason's Jar. It is in good vintage condition. I see no major chips or cracks. The top rim is really rough, but not sharp, I think some is chipped and some is from production. There are bubbles in the glass. We have hard water which made the bottom have hard water white resideue, it was on the outside on the jar also and just wiped right off. Please see photos carefully as they are part of the description.
