Cvault is the creator of a revolutionary new humidity-controlled curing and storage container for your herbs. The mission of CVault was to fix two problems that smokers face. Where should I store my herb, and how can I maintain a fresh and consistent humidity? After extensive research, CVault decided to use stainless steel for their containers material for lightweight, durable, and airtight storage that is also impenetrable to light. To address the humidity problem, CVault began working with Boveda/Humidipak to use their patented 2-way humidity control packet and discover the ideal humidity range of 58% - 64%. All you have to do is add your humidity pack to your CVault storage container and you will always have the freshest herb possible.
