Protect your acoustic guitar from cracking, warping, or worse with the Oasis HH Combo OH-30. This humidifier is a breeze to use. Just fit it into the soundhole of your steel-string acoustic, and it releases moisture evenly and slowly, while its built-in hygrometer takes all the guesswork out of adjusting humidity levels. The humidifier employs a drip-resistant sponge that holds 10 times its dry weight in water, so you won't need to refill it very often. The hygrometer is accurate, easy to read, and can be calibrated to your preferences. Guitarists know that safeguarding your instrument with a humidifier/hygrometer like the Oasis HH Combo OH-30 is a must.

Why do I need to worry about my guitar’s humidity level?

Changing weather conditions greatly affect the amount of humidity present. A typical acoustic guitar holds between eight and 10 grams of water. If the guitar's wood dries out, it shrinks. If it gets over-hydrated, it swells. Because your strings place a lot of tension on your guitar, shrinking and swelling can cause anything from fret buzz and fret-overhang to warping or twisting of the neck and top. And if you're really unlucky, your guitar will crack or split. That's why it's important to maintain a constant humidity level with a device like the Oasis HH Combo OH-30.

Here are some tips for protecting your acoustic guitar:

  • Store you guitar in its case when not in use and place a temperature/humidity gauge inside the case.
  • Keep the humidity level between 45%-60% inside the case. A guitar humidifier will usually do the trick, but it may also be helpful to use a room humidifier or dehumidifier.
  • 70 to 74 degrees Fahrenheit is ideal for guitars. Storing them away from direct sunlight or sources of heating and air conditioning will help to maintain a constant temperature.
  • Humidity control is like an extra insurance policy for the health and well-being of your guitar.

Great pre-reader book!
Format: Hardcover
As an early childhood educator, I use this book often for story time for children 3-5 years old. The book was recommended to our Museum by the Smithsonian Institution Early Enrichment Center. I ordered the book to share with my young granddaughter - I'm sure she will enjoy it as much as I do each time I read it!

Soft, convenient, mobility friendly
These work great for my father who has mobility difficulties. He’s able to maintain a better grip with these. The mesh is soft, not abrasive, to the skin yet works up a good lather. Standard bar ivory fits nicely with room for a bigger bar soap.

The perfect soap bag for me
I'm new to using soap bags, I've tried a few different brands so far and this one is by far my favorite. I love how soap bags create a rich lather with bar soap while exfoliating but the ones I tried before this brand were way too rough to use on a daily basis, my skin would be red after showering. When I saw the type of material these soap bags were made of, it looked to be more gentle so I decided to give it a try. I've only used the white soap bag a few times now but I love it. It fits my Dove soap bar perfectly (other soap bags were too large), still creates a nice rich lather and best of all the material is so much more gentle than the other soap bags I've tried so I'm able to use it regularly without feeling like I'm scraping my skin off. I was hesitant to buy these due to the lack of reviews but I'm glad I did, with how amazing this product is I hope more people find these and try them out. I plan to buy a few more packs in case they ever stop making these, the price is very reasonable as well.
