The CVault is what serious herb storage looks like when mason jars stop being enough. Built from 18/10 food-grade stainless steel, it is airtight, completely lightproof, and comes with a Boveda humidity control pack already included — everything you need to store herb properly in one container. Austin Vape and Smoke carries three sizes to cover personal use through dedicated at-home storage.

Why It Outperforms a Glass Jar

Glass jars let light through. Over time, UV and visible light degrade terpenes and overall quality in a way that airtight alone cannot prevent. The CVault eliminates that variable entirely — no light penetrates the stainless steel body, so what goes in stays in the same condition it arrived. The food-grade silicone gasket and engineered latch closure create a true airtight seal rather than a friction fit, and the Boveda pack sits in a dedicated holder built into the underside of the lid rather than sitting loose in the container itself. The containers are also stackable, and the lid surface accepts a non-permanent marker for labeling different strains or contents.

Three Sizes Available

The Small holds up to 14 grams and comes with one 8g Boveda pack. The Medium holds up to 28 grams with one 8g Boveda pack included. The Large holds up to 56 grams and comes with two 8g Boveda packs. All three use 62% RH Boveda packs designed specifically to maintain optimal herb humidity without over-humidifying.

Frequently Asked Questions

Why is the CVault better than a mason jar for herb storage?
Mason jars are airtight but not lightproof — UV and visible light degrade terpenes and overall quality over time. The CVault’s stainless steel body blocks all light entirely, and the engineered latch closure provides a more consistent airtight seal than a threaded glass lid. Combined with the included Boveda pack for humidity control, it covers everything a mason jar can not.

What does the Boveda pack do?
Boveda packs use two-way humidity control to maintain a precise relative humidity level inside the container — adding moisture when the environment is too dry and absorbing it when it is too humid. The 62% RH packs included with every CVault are specifically calibrated for herb storage. Replace them every three months or sooner with frequent use.

Which size should I choose?
The Small is ideal for personal daily carry amounts up to half an ounce. The Medium suits most home users storing up to an ounce at a time. The Large is the right choice for larger quantities up to two ounces or for anyone who prefers to buy less frequently. All three sizes are stackable so you can run multiples for different strains without taking up excessive space.
