The courier in a budget rental. The product was fine left on my porch but he also opened my garage door and then just left. But couldn’t tell Amazon in their problem report because this was the only space to complain. So hopefully someone that reads this product review will pass this info off to someone at Amazon. Product is just fine.LB

Item as described by the seller

A guitar needs a distinct level of humidity to play well, and to stay in tune, in wet weather or dry. Aside from keeping the best tones, humidity is needed to keep the wood stable. A dry guitar will give you cracks and splits, and costly repairs. You can buy a number of costly devices, but the guitar string makers, D’Addario, having given us these bags of a moist substance that do the same thing. If the climate is humid, so is the guitar. In atmospheres that make the tone woods dry, the humidity is absorbed by the wood. I started just to try. A week later, in winter, I could feel and hear the humidity rise. The sound was better, and also easier to play. I am convinced, now, that it has made my treasured guitar remain in good shape for a long time. Once you try, you may do what I did, ask Amazon to send you four different packages in a year. Near the end of one set of moist bags, you feel them being brittle. The next $18 moist bags arrive on time, and the proper moisturizing continues.

Best thing for acoustic guitars ever made

If you have a stringed instrument, it must be kept humidified to inappropriate level to avoid ruining either the woodcase or the sounding board and back. It’s in essential. This brand is the industry standard, and it works.If you have a stringed instrument, just buy this product, and don’t think twice. you need it. And this is the best.

No matter where you live, your guitar(s) need to be treated with respect. You shouldn’t leave them exposed to significant changes in temperature and humidity. Don’t leave your guitar in your car/truck/van unless you’re headed to a gig, jam session, or lesson! Don’t leave your guitar leaning against a wall or furniture when you’re not holding it - use a proper guitar stand for TEMPORARY breaks in the music. Storing your guitar in its case, when not practicing/performing, will help protect your beloved axe. (NOTE: Keep your guitar’s hard case closed all the time, except when removing the guitar or storing it after practice, etc.)Controlling the environment in your guitar’s case is IMPORTANT, too! A hard case is best because it can also be easier to control the atmosphere your guitar lives in.I use these humidity (restoration or maintenance) packs all the time in my guitar hard cases. I live in the subtropical Gulf Coast region of SE Texas.You might ask, “Why do you put humidification products in your guitar cases when you live in a humid environment? That doesn’t make sense and it sounds like a waste of money.”It DOES sound squirrelly, doesn’t it?Well, this product works TWO (2) WAYS to maintain the correct humidity level for your guitar! It can release OR absorb moisture inside your guitar hard case, keeping the headstock, neck, fretboard, top, bottom, and sides at optimal humidification.How often you have to replace the packs depends upon the climate and weather your guitar lives/works in and how you store it. Taking care of all that wood (and don’t forget the electrical components if your axe has ‘em) by preventing or mitigating cracks, swelling, joints and glued parts separating, etc., will help extend the life of your guitar and keep the coveted sustain and resonance going.Great product! I will continue using this company’s humidification products, for as long as I have guitars to take care of, so I can enjoy fingerpicking, strumming, and shredding.
