Make Your Jars Useful

That empty pickle jar, jam jar, or pasta sauce jar? It's probably still in your cabinet, rinsed out and doing nothing, because the flat lid it came with is only good or one thing–sealing. This stainless steel flip-cap lid changes that. Snap it onto any wide-mouth mason jar and it becomes a real drinking cup, a juicer lid, or a spill-proof container for the fridge or your bag–no new jar required.

FAQs

Will This Fit My Mason Jar?

Yes – this lid is made for standard wide-mouth mason jars (86mm opening), the most common size used for pickling, preserving, and storage. Just check that your jar is labeled "wide-mouth" rather than "regular-mouth" before ordering.

Is It Really Leak-Proof?

Yes–the flip cap seals tight against the jar to prevent leaks, so you can toss it in a bag, cooler, or fridge without worrying about spills.

Can I Put This In The Dishwasher?

We recommend handwashing with warm, soapy water to keep the seal in top condition.

Can I Use This For Canning?

This lid is built for storage, drinking, and pouring–not for shelf-stable canning, which requires a heat-processed vacuum seal from a traditional single-use lid. For jars you're using right away or keeping in the fridge, this is exactly what it's designed for.

What If I'm Not Happy With It?

We offer a 30-day money-back guarantee – if it's not the right fit, reach out within 30 days of delivery for a full refund.
