How this product never existed until now, blows my mind. It's simple, easy, cheap and so damn effective. All you have to do is tear open the packet, and inside you'll find a specially engineered cloth. Simply use this cloth to wipe down and season the inside of your humidor. When you're done, give it the ol' heave-ho. No more looking for new sponges or going to the store for distilled water. These wipes have been manufactured with propylene glycol and distilled water to provide everything you need. Perfect to keep on hand to restore a dry, or out of use humidor too. Once you use one, I know it's a well you'll keep coming back to.
