The 2-Way Humidity Control Packs are in high demand and now available for pre-order. The ETA is Oct 7-20. Reliable 2-Way Humidity Control Keeps your storage environment locked at the ideal 62% RH. When it’s too humid, the pack absorbs excess moisture; when it’s too dry, it releases purified water vapor to restore balance. Long-Lasting Freshness One pack maintains up to 1 oz of herbs for 3–4 months, preserving potency, flavor, and aroma. No more dry, harsh product—just smooth, enjoyable freshness. Safe & Natural Formula Made from a non-toxic salt-and-water solution, completely food-safe and worry-free. Convenient & Mess-Free Each pack comes individually wrapped for maximum freshness. Remove the outer wrapper and place it inside your airtight container—the pack does the rest. For best results, replace every 3 months. (Tip: Do not mix different %RH levels in the same container.) Versatile Protection Perfect for herbs, coffee, tea, cigars, and more. Also trusted for protecting guitars, wood instruments, camera lenses, antiques, and rare books from the damaging effects of humidity swings.
