Control the relative humidity of your instrument with an innovative system, introducing Boveda inside the case of your instrument. Depending on the size of the instrument, it is recommended:
Contains 2 packages of 49% (70 g) and 1 individual (1-pouch) fabric holder, leak-resistant. For electric guitar, electric bass, violin, viola, oboé, clarinet, ukulele and mandolin.
Contains 4 packages of 49% (70 g) and 2 double (2-pouch) fabric holders, leak-resistant. For classical guitar, acoustic guitar, acoustic bass, cello, double bass and bassoon.
Boveda ensures that your instrument is kept in optimal humidity conditions and therefore retains all its properties intact. The Boveda pack consists of salt, water and a gel solution contained within a water vapor permeable membrane. Inside a closed environment, Boveda maintains a certain level of relative humidity either by releasing or absorbing water vapor and eliminating all possible fluctuations in humidity. The Standard Wooden Musical Instrument Package is designed to maintain a relative humidity of 49%.
The technology behind the incredible benefits of Boveda and its bidirectional humidity regulation system is based on scientific principles according to the laws of Raoult and Henry. These principles are proven scientific evidence, not just theories. One of the principles contained within these scientific laws states that a saturated solution of salt in water will maintain a certain level of constant relative humidity within a closed environment. This immutable law is Boveda's fundamental principle.
We often find that several types of salts combined will produce the desired percentage of relative humidity. Boveda chooses the combination with the best capacity for moisture exchange and the least sensitivity to changes in temperature. In most cases, a given saturated solution will maintain a specific humidity level of +/- 1% over a wide range of temperatures.
That is why Boveda is so effective and easy to use, you just have to insert it into the case with your instrument and leave it.
