Bamboo Mason Jar Lids

The Bamboo Switch Bamboo Mason Jar Lids swap out single-use plastic and rust-prone metal for a cleaner, longer-lasting cover built from bamboo and sealed with a silicone ring that actually holds. Three sizes mean you can fit the lid to the jar you already own, whether that is a wide mouth for batch-prepped soups, a standard mouth for everyday storage, or the compact Oui Jar size for yogurt jars getting a second life.

• Silicone ring creates a reliable seal, keeping ferments, sauces, and dry goods fresh without the rust risk of metal lids.
• Three precise size options, Wide Mouth at 3.5 inches outer width, Standard at 2.8 inches, and Oui Jar at 2.6 inches, fit the jars already in your kitchen.
• Shipped plastic-free and made from bamboo, a fast-growing material that sidesteps the lifecycle problems of conventional plastic lids.

Hand wash with mild soap, dry thoroughly, and these lids stay in rotation for the long haul. A small, concrete swap that makes your storage setup a little less disposable.
