A Note about the Lifespan of Mason Jars
If you’re buying the DIY Kit, then you already have jars at home, and you probably already know this, but the metal rings and lids on mason jars can rust over time. We recommend hand washing and thoroughly drying your mason jar rings to extend their lifespan. The good news is that everything else can go in the dishwasher: glass mason jars, our silicone nipples, silicone sleeves, and plastic caps!
