WiseVial Snap-cap Desiccant Vial is a functional vial that integrates desiccant particles and plastic particles into the inner wall of the vial, giving the vial body moisture absorption and moisture resistance ability. WiseVial maximizes moisture protection within a limited space, allowing moisture absorption and drying effects to be better and more uniform. Plus, it can still be tightly sealed after repeated opening and closing, without worries about airtightness.
