When space is tight, the HUMI-CARE Slimline is just right. Thanks to a slim, compact design, this fits nicely into small spaces. Plus, the wider design also ensures a broad, even distribution of humidity. Just a quick dip in some distilled water will get this thing primed and ready to go. Each is ideal for 25-50-count humidors, making this three-pack good for up to 150 cigars!
