EcoPeaceful 316 Stainless Steel Mason Jar Lids, Regular Mouth – Leak-Proof, Vegan, BPA-Free

Meet EcoPeaceful 316 surgical stainless steel mason jar lids designed for regular-mouth jars. They blend rugged durability with a refined finish, delivering a versatile storage solution for everyday life at home, work, or while traveling. This is about rethinking what a lid can do when longevity matters as much as function.

The 316 stainless steel is chosen for its strength and moisture tolerance, while the 100% pure silicone seal provides an airtight, leak-proof fit. They fit standard regular-mouth Kerr and Ball jars from 4 oz to 32 oz, and they are not intended for canning projects.

We designed these lids to feel reliable in your hands: a substantial, cool-metal touch, a gasket that remains flexible year after year, and a seal that stays consistent. The silicone seal is vegan and free from animal-derived additives, and the design minimizes exposure to BPA, phthalates, or PVC. The packaging is plastic-free and shipped in recycled materials, aligning with a zero-waste ethos.
