They don't make many jars in this shape anymore. Perfect for shorter spaces, more efficient storage and making your pantry or gifts stick out from the crowd.

Use with any wide mouth jar lid.

All jars are guaranteed to be free of cracks and rust, though vintage jars can have very slight "flea bites" in the rim or other small cosmetic chips that do not affect the performance of the jar.

This listing is for one jar as shown. Jars do not come with a lid so that you can choose exactly what you want here: wide mouth jar lids.

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.
