WHY THIS BOVEDA: 75% RH OVERCOMPENSATES FOR LOW RH in leaky NON-PLASTIC cases; high altitudes; dry climates; sticks that finish too quickly; or if you prefer a more-humidified experience. Use one 5.25"x3.5" humidifier packet for every 25 TOTAL items your humidifier box can hold. NATURAL INGREDIENTS. Trusted by over 3 million people to protect & maintain items at the perfect humidity level. WE GUARANTEE QUALITY! | HOW BOVEDA WORKS: Boveda 75% RH keeps items fresh by stabilizing the humidity inside a humidifier box. If the air inside your container is too moist, Boveda absorbs that moisture. If it's too dry, Boveda releases moisture into your container to bring what's inside back to life. ADD A BOVEDA PACK RIGHT AWAY TO A HUMIDIFIER BOX WITH NEW PREMIUMS. You can also use Boveda 75 to restore overly dry items to their original flavorful, aromatic state-the way the master blenders intended. | CHOOSE BOVEDA: Boveda's the only patented 2-way humidity control solution with 25 years of experience. Using saltwater in our humidity packs, we provide the fastest, most precise humidity control in the market. Boveda is the only humidity solution that can do so within 24-48 hours. | HOW TO USE: NO MORE REWETTING SPONGES, REFILLING BEADS, OR ADDING MORE GEL! Remove a moisture pack from the resealable bag, slip the Boveda 75 humidity pack into any NON-PLASTIC humidifier box, add premiums, & close the lid. BOVEDA DOES THE REST. DO NOT cut or open the brown humidity packet. Replace every 3 months. You'll know it's time to swap out Boveda when it becomes hard and crunchy. NEVER MIX the 75% with any other %RH. | WHO IS BOVEDA FOR: Aficionados fine-tune their humidifier boxes with BOVEDA 75% RH FOR CHALLENGING CONDITIONS, such as low RH in starter boxes, leaky wood boxes or glass-topped containers; desert climates; dry seasons; and high altitudes. Stop struggling with low RH in your humidifier box or putting up with dry sticks that finish too fast. THERE IS A ZERO MAINTENANCE HUMIDITY CONTROL SOLUTION-Boveda.
