At Mason-re we continue to innovate with the world's first silicone koozie for the 4oz mason jar paired with an eco fiber child resistant lid to create the perfect reusable stash jar. As usual 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. Re:stash Includes: (1) 4oz silicone koozie (available in many colors) (1) regular mouth child proof lid (available in white or black) (1) 4oz mason jar
