WiseVial Snap-cap vial with desiccant capsule is designed to conveniently pack the right amount of medications, prescriptions, and test strips. The vial lid features a built-in compartment filled with a non-toxic, cobalt-free silica gel capsule with powerful moisture absorption capacity. The desiccant capsule changes color as it absorbs moisture, starting to change at 20% relative humidity. This allows customers to monitor the internal humidity even after opening the vial. The desiccant capsule is replaceable, and the vial color and sizes can be customized.
