Weck glass jars have been a mainstay in European kitchens since 1900, when German merchant Johann Weck pioneered the science of water-bath canning. Weck jars are still a reliable favorite of European home cooks for preserving and storing foods. These jars feature a tapered shape that is easy to fill. Rubber-ringed glass lids create an airtight seal that you can check at a glance. 

  • For preserving foods using boiling-water canning; also useful for storing dry food staples in the pantry.
  • Wide-mouth tapered shape makes the jars easy to fill and handsome enough to bring right to the table for serving.
  • Each clear glass jar comes with a glass lid with rubber ring and two rustproof stainless-steel clamps for creating an airtight seal.
  • Seal is easy to check at a glance: the pull tab on the rubber ring should face downward.
  • Embossed with the Weck strawberry logo.
  • Stackable for convenient storage.
  • Replacement rubber rings and clamps are available (sold separately).
  • Set includes 6 jars, 6 lids, 6 rubber rings and 12 clamps.

  • Rated 4 out of 5 by from Classy Storage I love these glass jars for how they look and the size. I store grains and flours in them. The only thing that is frustrating is that the rubber rings get stretched out easily.

    Rated 5 out of 5 by from Store, Share, Reheat & Enjoy These 12 oz jars are perfect for us. We're not canning. We make healthy soups, stews, pasta dishes and more, and store/freeze them in these fabulous jars. We share these foods with the younger generation who enjoy the food right out of the jars, and return the jars, lid, clamps and rubber rings for more. Gives them just a little more time to enjoy their young kids. Love these jars! Easy to fill, wash, and even easy to open with pull tab rubber rings.

    Rated 5 out of 5 by from Handsome Food Storage I use these great looking jars for leftover storage and for those partial jars of jams and pickles. They are attractive & stylish and can go from the refrigerator straight to the dinner table. Lids fit tightly and they stack extremely well. Bonus feature - They really makes the refrigerator look sharp! If you have one of those "smart" refrigerators that you can look in on your phone, you'll want a couple sets of these for the maximum impact!

    Rated 4 out of 5 by from Perfect size These were good quality and are stackable. They look great -my only concern was the rubber seal, it takes an extra minute to get it on to close properly. These were a solution to moving away from plastic for storage.

    Rated 4 out of 5 by from Functional and versatile I like these jars. They are easy to use and easy to clean. I do not use my jars for canning or preserving. I simply use them for storing foods in the pantry and the fridge. They also work really well for taking my lunch to work be it granola, fruit salads or carrot sticks. I don't like to use plastic for storage so these glass jars do the trick. The clips can be a little difficult to work with when securing the lid. I have mild arthritis and it can sometimes cause me discomfort to fight with the clips. But overall, the jars work as intended for me.

    Rated 3 out of 5 by from Weck mold jars These jars are of exceptional quality. The wide mouth makes filling and serving very easy. However the rubber rings are extremely thin and flimsy and I would not trust them to seal, so I will not use them for canning.

  • Can the rubber rings be re-used for canning?

    Asked by: Elizabeth
    Hi Elizabeth, Once the rubbery seal on the lid is heated and cooled, it can’t make the same quality of seal again. And since the quality of the seal is essential to preserving what’s inside the jar, they should not be reused.

    Can you take soup to work in this jar without leakier ng in the lunch bag?

    Asked by: rapunzel
    Hi rapunzel, Yes, if this is clamped correctly, the tab on the rubber seal will face downward and the seal will be leakproof.
