I love this cigar “coolant” ! They work great & at this price it’s way less than most cigar shops!

I use these in my humidor great price and the work well!!

Excellent item with an amazing price. I was on holiday in the states and bougt this while at the hotel as it much more expensive here in the UK.

1. subjectively, it appears distilled water works best, but fungus will grow in the humidifier (guitar or cigar).2. so far the propylene glycol (pg), seems to control the fungus (i haven't seen any since i started using it).3. the sponge doesn't dry out as quickly as with only water, but i think this means less water is released to the cigar or wood (i use for guitar).4. since it controls the fungus growth, i can recommend it; i suggest you experiment so that you have the most water possible in the sponge and enough pg to control the fungus.

Great product to assist in keeping your cigars fresh and humidor at its optimal level
