Replacement Pouch for Stretto Humidifier for Cello and Large Instruments: Pack of 4

The backing of these Stretto’s are different from the ones I bought earlier. They don’t last the 3 weeks as they did before; for me, they last about 4-5 days; that’s it! . Since then, I’ve been having a hard time getting help from anyone within Amazon. Should I look for another place to by them from?

I use these for the dozen or so stringed instruments in our home (family of musicians). They are the best humidifier packets on the market. However, occasionally I will get a shipment with much less gel crystals inside so the packets don't plump up as much a s usual no matter what I do including letting them soak for hours. Then the next shipment is fine. It seems like their quality control has gone a little bit down hill in the past ten years.

I use these with the corresponding stetto humidifier thing in my cello hard case, but every single one in my pack have turned brown and all the bead things have clumped together, making it unusable. I then tried just wetting one and letting it sit out on the counter until it was dry to make sure it wasnt my cello case causing the clumping, but it did the exact same thing.

All like it was advertised on the website. 👍🏽

I have a dry apartment and two winters ago a crack formed in my cello. After having it repaired I purchased this product and had no problems. It kept my cello in great shape.

Best gel-based humidifier I have found for my instruments.

Simple product

... work very well, ... my wife keeps it in her Cello case always and the humidity is constant ...
