A beautiful addition to any collection, these jars were manufactured in the 1950's and 60's.  They are heavier and more detailed than their similar more modern counterparts.  These jars are no longer in production.

A staple of the canning and storage world, this wide mouth jar is the perfect size for:  

  • A stylish and eco-friendly water jar.
  • Store dry goods in your pantry, easily pour and measure dry ingredients from the large opening.
  • Freeze perfect soup portions for two.
  • Make smoothies in bulk, add all the ingredients to a jar and store until you are ready to thaw, blend and sip.
  • Canning tomato sauce, stock, salsa, or the season's fresh fruits and veggies.
  • Bring your salad to work, add a Cuppow BNTO bento cup to store your salad dressing
Use with any wide mouth jar lid.  Square body makes for more efficient pantry or freezer storage.
Jar is smooth and clean on three sides (perfect for crafting!) with the Kerr logo on the front.
