Why do I feel small crystals or hard lumps inside my Boveda?

Our formulas are a saturated salt solution which means an excess amount of blended salts are mixed with water and dispensed into the pouches you receive. From time to time some crystals form during the blending and filling process. This is normal and inherent of salts physical structure but also unavoidable. Although crystals will form, they do not impact the performance of Boveda and are completely safe to use.  If the crystals have become too sharp, and in the rare instance puncture the pouch, please notify Boveda and we will replace them at no cost.
