Is this a vacuum sealed container? The same volume of air as the cap is removed and for human purposes this is enough to keep most goods fresh and edible for long periods of time. For the engineers out there technically speaking there is no vacuum until the cap is pulled upward without pressing the button. The airtight system is able to preserve goods for 1 year and beyond by allowing products to breath and degas. Almost all food goods are smell proof inside the Vacs, however some products like freshly roasted coffee and medical herbs may degas, leaking there odor. Our 2 way valve allows gas build up to slowly escape without letting oxygen in. This is one of the main reasons it can preserve goods for long periods of time. Is it moisture and oxygen free? Yes the airtight system keeps moisture and oxygen out - these elements cannot enter the container unless you decide to take the cap off. Note: Medical herbs that are sticky and smelly we recommend using a strong zip lock bag inside the Vac. This helps contain the smell and keeps the area clean where the body and the cap meet. This is essential to create a smell proof situation. The sticky resin often created by these products can compromise the open and close system, causing the caps to crack when opening and closing under such pressure of a glue like substance. Keep these areas free from resin buildup. Use a product like Grundge off. Thus maximizing the efficiency of use and longevity of the Vacs.
