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

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

Works amazing and keeps product really fresh. I'm in FL and find these work better than the 63 due to the humidity here.

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.

The 58% is perfect for my needs the 62% is ok but harder to light and stay lit when using the "product" it was keeping fresh. Highly recommend the 58%. Also they say to change the packs every 3 months. I store my "product" in 2gal food safe containers. So I use the 1 pound packs (size 67). They have lasted about 18 - 24 months!!I keep Hygrometer's in my buckets and it is quite amazing how accurate the Boveda humidity packs are. The % is always exact or within 1%. The Accuracy is VERY impressive!

I like them the product helps very effectively with managing the curing process of my harvest makes the job much easier It does perform as stated .However it is very expensive ad I cant really say that I think it is good value for the money because of the high price. It is very important to control humidity levels in the curing stage and this product will do that . They also come in handy sizes for your canning jars

Works as described, easy to use, and good price. I have bought these several times and never had issues.

This was my first time trying the 62% Boveda pack, and I’m honestly impressed. I used it to store herbs, and it kept everything perfectly fresh with no dryness, no moisture issues, just consistent humidity.Super easy to use, just drop it in and forget about it. No maintenance, no guesswork. I’ll definitely be using Boveda again

works like a charm and keeps my plant materials at the exact perfect humidity every single time. I use hygrometers to double check the accuracy of the boveda packs and its been right 100% if the time and ive been using them for years now. they are affordable and they last quite a long time.
