Meet the Maker
Hi, I’m Marie, the heart (and muscle) behind Mason Jar Merchant. For me, mason jars are so much more than containers! A gift of beautiful vintage jars from my husband’s grandmother sparked a personal love for these versatile jars that quickly grew into a passion and I love sharing their possibilities with others.
As my collection grew, so did my creativity. I began crocheting cozies, painting lids, making custom straw tops, and of course, mason jar tumblers.
Today, Mason Jar Merchant is about more than jars—it’s about empowering people to live healthier, more sustainable and resilient lives. Every product we offer, from vintage jars to lids, tumblers, and accessories, is chosen with the hope that it inspires you to reduce waste, eliminate plastic, and embrace the simple joy of practical beauty.
