Optimal preservation & control - The 'Mary Purple' offers the highest protection against UV light of all known glass types (e.g. amber glass, blue glass, green glass, clear glass) thanks to the violet glass. Thanks to the integrated hygrometer and the Boveda Hygro-Pack you also have the humidity always under control. This not only preserves the potency and flavor of your grass, you can also refresh flowers in poor condition.
100% Glass - 100% Taste - Thanks to the unique glass cut, the Mary in a Bottle does not need a sealing ring made of plastic or rubber, as in conventional canning jars. Plastic and rubber not only become brittle over time, but also give off fumes in the long run that negatively affect the taste.
