Weck Canning Jars 742 - Weck Mold Jars made of Transparent Glass - Eco-Friendly Canning Jar - Storage for Food, Yogurt with Air Tight Seal and Lid - 1/2 Liter Tall Jars Set - (2 Jars)

Bought these smaller sized ones after I had the larger sized ones for sourdough. Good quality jars.

The WECK 742 Mold Jars combine practicality with an understated design aesthetic that makes them feel equally at home in a working kitchen or on open shelving. The thick glass feels substantial and durable, while the classic silhouette gives even simple pantry storage a more intentional, refined look. What stands out most is the versatility. They work beautifully for canning, but also for everyday storage—ferments, overnight oats, dry goods, sauces, or prepared ingredients. The wide opening makes them especially easy to fill, clean, and use repeatedly without frustration. The sealing system also feels thoughtfully engineered. The glass lids, rubber gaskets, and metal clips create a closure that feels secure without relying on disposable plastic components, which adds to the sense of longevity and craftsmanship. There’s a quiet satisfaction to using them daily. They turn ordinary kitchen routines into something slightly more tactile and deliberate.

J’adore!!

Perfect for the sourdough baker who keeps a small(er) amount of starter on hand. I keep mine in the refrigerator and only bring it out on baking days. I usually keep about 10 - 20 grams in the jar and there's plenty of space to feed it up to the 125g I normally use for a loaf. The clips were a little tricky at first, but work well to keep the lid on tight and the rubber o ring in place. The wide mouth style of these little jars is much easier to work with than my tall, narrow jar.

Thick glass and great quality. Perfect for storage or canning and looks nice on the shelf.
