The Cigar Caddy Crystal Gel Humidifier Jar is designed to effectively maintain humidity at 70%. The super absorbent polymer crystals absorb up to 100 times their weight in fluid. As they lose moisture, they shrink so you know when it's time to refill. Safe, effective, and very easy to use!

These units now come dry. You will need to fill with a "use every time" solution (like Cigar Caddy or Xikar brands). Or, you can use a 50/50 PG solution for the first fill and then distilled water thereafter.

• Slow, Steady Release of Constant Humidity
• Lasts up to 90 days before refill
