The Mason-re team created the world's first silicone koozie for the 4oz mason jar and paired it with an eco fiber child resistant lid to create the perfect reusable stash jar. The koozie fits like a tailored glove and is made from 100% silicone. Our lids are made in America from FDA Polypropylene that is 30% re:purposed farm waste and hemp fibers, allowing you to store your stash safely away from children as well as sunlight.
