Includes stainless steel band! Unlike normal Mason jar rings, this one will not rust with normal use and is dishwasher safe.   Our lid is dishwasher, freezer, and microwave safe! Plus silicone is a safe, green, non-plastic (BPA free) material for food use that does not leach any chemicals.   A half pint jar with a regular mouth drinking lid makes a perfect toddler cup / sippy cup! Add a silicone koozie to protect the glass from breakage! Our kids love to use these for hot cocoa in the car and fruit smoothies on the go and we love that the beverage stays contained and the kids (and car) stay clean!   Plus they also work great with a straw (up to 8mm for wide mouth or 6mm for regular mouth). We love how they grip the straw and hold it in place. Who doesn't love options?!   These drink toppers will fit on any jar - half pint, pint, pint & half, quart, and even half gallon (if you are really thirsty).   Made from 100% food grade silicone rubber and 18/8 304 grade stainless steel.   We upgraded these from FDA (American standard) to LFGB (European standard, higher quality) silicone, which means they now pass the "pinch test." There are still a couple variations that haven't switched over yet.
