Ball Perfect Mason Jar Pint 9 Ribbed Square Clear Glass 1923-1933.

There are 9 gripper ribs on this jar, 3 on each side and 3 on the back.

The number 2 is under the words perfect mason and I believe the number 3 is on the bottom of the jar.

Good to Very Good pre-owned condition.  No chips, no cracks, no repairs.  Average minor wear. 

Please refer to the photos for condition.  Feel free to contact me if you have questions or need additional photos.
