A staple in European kitchens since 1900, German-made Weck jars feature flat-top press-on glass lids secured with stainless steel spring clamps. As canning jars, they are easier to use than screw-top Mason jars; as storage jars, they are attractive and easy to clean. The jars have a neat, subtly tapered shape and feature Wick's vintage strawberry logo pressed into the lid, which gives them a charming vintage appeal. The wide openings are easy to fill and scoop from, and—thanks to their specially grooved flat tops—they stack neatly and securely in crowded pantries.
