Boveda75% Two-Way Humidity Control Packs – Size 60 – 12 Pack – Fix Major Moisture Loss/Low RH in Non-Plastic Humidifier – Moisture Absorbers– Humidifier Packs – Individually Wrapped Hydration Packets

I have a guitar collection to care for so I bought this product and my guitars were protected during winter. One of my guitars showed some signs of lack of humidity and after I used this product they disappeared and my guitar was like new. I recommend this product.Update: One of my favorite guitars, a custom built classical, developed severe dryness of its fretboard. It shrunk so bad that all frets were sticking out making it unplayable. How this happened? It was my fault as I neglected to keep a supply of Boveda pouches. Anyway, I didn't want to pay big $$$ to have it fixed. I ordered a box of Boveda's 84% pouches and incerted two inside the body and 2 on top of the fretboard which was held in place by just closing the hardshell case. Last night, after several weeks, the fretboard was like new, no sticking frets and a delight to play. This product is worth every penny. Boveda's humidity system will be the only thing I'll use to maintain my babies in excellent playing condition. Again.. I highly recommend it.

They're definitely a great product! For my cigar humidor, I use one packet of 72%. Each last about 3 or 4 weeks..maybe little longer depending on how often you open the lid on humidor. No longer need to rely on a hygrometer! Highly recommended..but a little "pricey".

I get the 75%. They keep my humidor at around 70. Buying in bulk is cheaper and easier than going to a local cigar store. Good product and more effective than those little plastic humidifiers with special solution which never really get the humidity to the correct levels.

As a moderate cigar enthusiast I found it difficult in the beginning to find a good way to control the humidity in my humidor especially with a busy life. Someone recommended Boveda Humidipaks and I haven't had a problem since! I can get busy in personal life for several months and don't have to worry about my cigars every week anymore. I do recommend writing the date on the pack when you put it in and my particular humidor takes two which I rotate out about every 6 weeks. Each pack tends to last close to 3 months if your not constantly opening the box but I imagine it varies on the humidor. After a little playing around with how many packs and length of time, my humidor has been consistent for several years. I highly recommend this product!

Nice quick and clean alternative to distilled water on a sponge. Keeps cigars fresh.

Keeps my humidor perfect

Fantastic products, the version I purchased I used to help set the initial humidty level and to season my humidor. Simple clean and easy product that makes your life easy.

Have been using this product for couple years now and it does exactly what is intended to do. If you like me sometimes I will be lazy and not stay on seasoning my humidor so simply put the packets in and you good to go. Have a 100 capacity humidor and usually use two packets on top of crystal jar during the more dry air months and it works like a charm.
