AIRTIGHT STORAGE ISN’T ENOUGH! Maintaining the right relative humidity has an enormous impact on preserving the aroma, flavors and potency of your items. So DITCH THE BARGAIN BAG and time wasted adding a humidity pack! The 1 Pound Boveda Fresh Bag is a premium, REUSABLE, multi-layer, 4.5 mil construction storage bag that keeps large amounts of items FRESH FOR MONTHS with a Boveda moisture pack already included inside! This large, airtight 16” x 16” bag is designed for longer-term bulk storage, and the 8” gusseted bottom opens to sit flat when filled. The Boveda Fresh Bag will keep the contents fluffy and bouncy—NO DRYNESS! The simple but powerful zipper makes accessing your items FAST and CONVENIENT! The Boveda Fresh Bag preserves the QUALITY of the contents inside better than any other bag with the precise and patented power of Boveda. If the contents in the bag are too moist, Boveda will absorb the excess moisture, and if the contents are overly dry when you fill the bag, Boveda will release moisture to rehydrate your items and keep them in the 55%-65% relative humidity (RH) “safe zone”. Simply replace the Boveda pack just before it expires (when it is almost completely solid and before it becomes rock hard). Boveda has been maximizing people’s passions for over 25 years, when our founders and scientists developed and patented a way to precisely maintain the relative humidity of moisture-sensitive consumer items using a saturated saltwater solution. This simple-to-use brown packet has become the industry standard for precise and stable 2-way humidity control.
