Did you know peanut butter jar lids fit mason jars? One TikToker just blew everyone’s mind by swapping out rusty metal lids for plastic PB ones—no more tossing jars just because you lost the lid! It’s a total win for saving money and cutting down on waste. Just don’t use this for canning, but for snacks, leftovers, or random stuff? Genius. Someone even suggested Parmesan cheese shaker tops work too! Would you try this hack? #News #LifeHack #SustainableLiving
