Our 3.5 gram jars have corresponding airtight lids that make them smell proof, ensuring all of your herb’s enticing aromas remain inside the jar. The lids close off the containers, sealing in the scent of the cannabis and preventing any of it from escaping. This attribute is a primary feature for marijuana packaging items, as most users prefer to practice discrete consumption. It also contributes to extending the shelf life of weed by inhibiting excess oxygen and other contaminants from penetrating the packaging.
