Boveda 58% Two-Way Humidity Control Packs For Storing ½ oz of Product – Size 4 – 10 Pack – Moisture Absorbers for Small Storage Containers – Humidifier Packs – Hydration Packets in Resealable Bag

I couldn’t be happier with these Two-Way Humidity Control Packs. They do exactly what they’re supposed to—maintain a consistent humidity level without any guesswork. Whether you're storing cigars, instruments, important documents, or specialty items, these packs keep everything perfectly balanced. What I love most is that they both add and remove moisture as needed, so you don’t have to constantly monitor conditions. It’s truly a “set it and forget it” solution. They’re mess-free, easy to use, and last a long time. Since using them, I’ve noticed a big difference in preservation and overall quality. No more dryness, no more excess moisture—just steady, reliable performance. Highly recommend for anyone serious about protecting their valuables!

Works well

Boveda is the gold standard in maintaining humidification for musical instruments. They offer a specific set for large instruments such as guitars. This set contains three packs at 49% humidity each. If you live in the Northeast, that set is perfectly adequate to maintain your guitar's humidity at the recommended range - between 40 and 50% - for eight months out of the year. HOWEVER.... from November through end of February, those packs are unlikely to win the battle against winter dryness As I found out the hard way: cracks started appearing in a prized vintage guitar which (I thought) was fully protected by 49% boveda packs. When i checked the hygrometer inside the case, it read 30% - so, not so much. I had it repaired by my luthier and asked him if there was any way to prevent this from happening again. He said get the 58% packs - put them in on Halloween, replace them with the 49% packs on St. Patrick's day. Problem solved! During those months the 58% packs functioned perfectly. Guitar humidity never varies from 45 to 47% and I've avoided another $300 unexpected repair bill. Highly recommended

I put this inside my flute case to help control the humidity inside when I travel. My flute is very finiky to temperature and this works great at keeping it in tip top shape!

Always work great, great for herbs, just toss in and let be!

I've been using Boveda humidity control packets for over 10 years, and I can confidently say they are an absolute game-changer when it comes to maintaining the perfect environment for my items, whether it's cigars, instruments, or even just stored goods. Over the years, they have never failed me. What sets Boveda apart is their consistency and reliability. I use them regularly to keep my cigars in prime condition, and each time, they maintain the ideal humidity level with ease. The packets are incredibly easy to use—just place them in your storage container, and let them do their job. There's no mess, no fuss, and no need to monitor constantly. They automatically regulate the humidity, ensuring that it stays within the desired range, and I never have to worry about my cigars drying out or becoming too moist. Boveda packets also last a long time, making them a very cost-effective option. Over the years, I've found that they continue to deliver great performance and durability, with each packet holding up for a significant period before needing to be replaced. The fact that they don’t require any activation or added maintenance makes them incredibly convenient, and their long-lasting effect means I get great value for my money.

These are great to keep your bud fresh

I've been using Boveda 65% to keep my cigars for many years, but there were signs of overhumidification such as mold in my cigar stash. So, I made a decision of switching 65% to 58% for a change. After just several days of utilising them, humidity is slowly but steadily reduced to 64%. Although it'll take some time to decrease humidity even lower, I'm really happy with them since it was stuck at 67-68/69% all the time when I was using 65%. I highly recommemd to try Boveda 58% for those who're struggling with high humidity and using airtight containers inluding tupperdor (humidity can be higher in these vessels) like me.
