Give tiny hands a grip they can hold onto.

Mason Bottle's silicone sleeves wrap snugly around your glass mason jars or PureSip™ stainless jars, cushioning every drop and adding a soft, textured surface that's easier for babies (and tired parents) to hold onto than bare glass. A clear viewing window with embossed ounce and milliliter markings means you can check portions at a glance.

Beyond drop protection, the silicone adds light insulation to help keep contents at a more consistent temperature, and it wipes clean or goes straight into the dishwasher.
