Size 4 iHumi 2-Way Humidity Control is perfect for small medicine containers, small bags and pre-roll tins.

Place humidity pack in packaging and/or storage for precise Relative Humidity (RH) to protect all the good stuff (terpenes, cannabinoids and flavonoids). Also prevents mold or overdrying.

Choose 58% or 62% RH—a personal preference depending on how you prefer your experience or on what the humidity level is where you are. Some prefer 58% RH for personal-use products or 62% for larger herbal storage.

All-natural salts and purified water inside keep terpenes protected for 2-4 months in airtight containers. Just place Size 4 in a container with up to 15 g. Replace when humidity pack is rigid.

Preserves the aroma, flavor and effectiveness until after the grind. Boveda creates a monolayer of purified water molecules that naturally coats trichomes to shield terpenes and cannabinoids preserving the smell, taste and potency until use.

Do not mix humidity packs RH levels within the same container, and do not use iHumi in the same container with other humidification products. They will fight against each other and reduce the efficiency of this product.
