These vintage pint Ball ribbed clear-glass freezer jars and zinc caps are in very good condition

Made in USA

One side of the jar is embossed with the words Ball FREEZER JAR

The words ALLOW 1/2 INCH HEAD SPACE and PAT. PEND. are embossed on the other side

Including the zinc cap, the jar is approximately 5" tall

As expected with vintage canning jars, there are manufacturing flaws including bubbles in the glass. The jar shows wear consistent with its age and purpose including rim wear and surface scratches
