Maintain perfect cigar freshness with the XIKAR Crystal 100 Humidifier, a simple and reliable solution for long-term humidification. Designed to keep up to 100 cigars at an ideal 70% relative humidity, this crystal-based system slowly releases moisture as needed, ensuring consistent performance without over-humidifying your humidor. The crystals absorb Propylene Glycol solution, expanding to full capacity and gradually shrinking as they release humidity, so you know exactly when it’s time for a refill. Compact, easy to use, and maintenance-free for weeks at a time, the XIKAR Crystal 100 keeps your cigars in perfect smoking condition, just as the maker intended.
