What to know before buying

Listing details to confirm

Listing details are inconsistent: it identifies a guitar soundhole humidifier with a hydrophilic sponge, but also lists corded electric power, touch controls, 20 litres capacity, a one-minute runtime and bedroom use. These appliance-style details do not clearly describe this guitar accessory, so confirm the selected listing’s actual configuration before buying.

It is presented as a soundhole humidifier for acoustic guitars, intended to release moisture gradually and help limit drying while the instrument is stored.

What material does it use?

The listing specifies a hydrophilic sponge and claims that it holds 12 times its dry weight in water.

Are the listed capacity and electrical details reliable?

The listing pairs the guitar humidifier description with appliance-style claims such as corded electric power and 20 litres capacity. Those details are inconsistent with the product description, so confirm them rather than treating them as settled specifications.
