Glass containers are particularly popular because they offer a hermetic seal that prevents the penetration of air, moisture, and light—factors that can degrade the weed over time. These containers come in a variety of sizes and shapes and offer an easy way to keep your weed clean and safe. They often feature an airtight seal to create a fresh environment that can preserve the flavor and potency of the herbs for longer. Glass containers are also flavorless, so they don't impart any flavors or chemicals to the weed, thus preserving its natural taste.
