Well on the jar that does not matter, it does say Ball in big bold letters, Mason in smaller letters. My family always called them Mason so I never noticed the "BALL".
I just bought one for something a couple of weeks ago and regretted that it was made in China. I guess they are conserving that big pile of sand.

Culpepper if you notice in the jar there are a couple of loose flakes of Unique in their, I guess if I was drinking from it things might of gotten a little loopy.
