Our MJL silicone sleeves provide insulation, added grip, and padding to reduce the risk of breakage – plus they’re super cute! The silicone liners are perfect for sealing up your premade Mason jar for leakproof, on-the-go baby feeding. Plus the rustproof, stainless steel bands will provide longevity of use and can be used later with a silicone straw hole or drinking lid as baby grows up!
