Fresh-Port® Wide Mouth Mason Jar Lid

Rethink Glass Jar Storage 

The Fresh-Port® Wide Mouth Mason Jar Lid by Cannascape® transforms an everyday mason jar into a high-performance cannabis storage system. Designed to fit any wide mouth mason jar, this airless lid transforms a classic jar into a high-performance cannabis storage system. When paired with Airgone® Argon Gas, the Fresh-Port® valve allows oxygen to be flushed out, creating a low-oxygen environment that helps preserve the potency, flavor, aroma, and freshness of your flower.

Simple to use and easy to clean, this silicone lid is reusable and made for all types of cannabis users, whether you’re storing your latest harvest or just keeping your stash fresh between sessions. A built-in strap on the underside securely holds a Boveda® Pack, helping maintain proper humidity levels for optimal cannabis storage.

Our Mason Jar lid works with Fresh-Port® technology, which allows inert gases such as Airgone® Argon Gas to be sprayed onto moisture-sensitive products for added protection. Along with a degas valve, allows contents that emit gases such as CO2 to self-burp, making this inner lid self-degassing.

Using the Mason Jar lid is simple: slip it onto the jar, insert the Airgone® straw into the Fresh-Port® valve, and apply a quick one-second flush. Argon sinks below the oxygen, forming a protective layer that helps preserve the freshness of your cannabis. 

A quick note when using Airgone®! There is a wear-in period when using Airgone® with the patented Fresh-Port® Wine Topper. Some customers may experience some resistance when inserting the red Airgone straw, and this is entirely normal! These lids were designed with narrow valves to ensure no sneaky leaks or oxygen exchange could harm your product.

For optimal results when using Airgone®, keep the red straw detached from the Airgone® can when inserting it into the Fresh-Port® valve. Hold the red straw close to the end being inserted and apply gentle pressure until the straw can stand alone. Then, attach the Airgone can to the opposite end and administer a 2-second flush to displace oxygen. Once worn in, customers should have no trouble using Airgone® to keep their products fresh.

If you would like to speed up the wear-in process, take a paperclip and poke the blunt end through the Fresh-Port® valve. This should help widen the valve slightly while maintaining the silicone seal, preventing oxygen exchange!
