From the Super Collection. The Super Collection of rounded and terrine-style Le Parfait jars has been made in France since the 1930s and recognized worldwide by award-winning chefs and home cooks alike for durability, beauty and versatility. The extra-wide mouths of these jars allow for easy access to food and the attached glass lid and natural rubber seal system provide an airtight and watertight seal for the contents inside. Use these jars for storing bulk pantry goods, canning in-season foods en masse, making infused beverages, small-batch fermenting, zero-waste lifestyles or even for your next cold-brew coffee or tea. The rounded bodies of the super jars make them ideal for fresh produce and sauces while the straight-sided (slightly conical) bodies of the super terrines make them perfect for meats, seafood and layered creations. The possibilities are endless with the Le Parfait super wide-mouth collection of jars! The brilliantly clear glass provides a view of the freshness of the food inside and the glass will never stain or retain odours. The lead-free glass is also 100% recyclable and food safe for dishwasher, freezer and microwave use. Enjoy the beauty, design and function of 'the perfect' jars! Why is glass sustainable? Glass is made from all-natural raw materials, is easy to sterilize and reuse, and is 100% recyclable-meaning a glass jar can become a new glass jar over and over again!
