No, it's not gremlins

Every musician has heard the horror stories: Cracked finishes, warped necks, loose glue joints, sharp fret edges, or even collapsed tops. It often feels like the instrument has fallen victim to some mysterious, malevolent force. Thankfully, it's not mischievous gremlins lurking in the dark – just less than ideal humidity. Wooden instruments are sensitive to their environment, only really remaining stable when stored between an ideal humidity range of 40% and 60% at room temperature. Maintaining that balance is simple with Boveda 49% – a reliable, low-maintenance, two-way humidity control solution that protects valuable instruments without any hassle or high costs.

Three months of humidity control

Boveda uses the natural process of osmosis to maintain the ideal humidity level. Inside each individual Boveda 49% pack is a specialised salt solution that automatically balances moisture levels – absorbing excess humidity when the air is too damp and releasing it when conditions are too dry. This helps keep the humidity level very close to 49% (hence the product's name), which is ideal for wooden instruments. This simple, self-regulating system provides hassle-free protection for all wooden instruments. Just place the pack – in its special sleeve – inside the instrument case, ensuring it's not pressing against anything, and it will maintain stable humidity for up to three months. When the pack hardens, simply replace it. Regardless of the season – whether it's dry indoor heating or humid summer heat – Boveda keeps instruments consistently and reliably protected.

Keep your instruments safe!

The Boveda 49%-HA Size 40 4-Pack is designed for all wooden instruments – from ukuleles to double basses – offering reliable humidity control across a wide range of sizes. For added safety, the packs should always be used with a Boveda sleeve, which prevents potential leaks in the rare event of breakage and protects the instrument's finish from direct contact damage. This set includes four smaller 40g Boveda 49%-HA packs, ideal for refilling existing starter kits and ensuring continuous protection of valuable instrument.

About Boveda

Since 1997, Boveda has been a leader in humidity control solutions. The company was built on the innovations of Dr. Al Saari, who developed a unique salt solution, and packaging expert Robert Esse. Their pioneering efforts have resulted in patented packs that provide reliable humidity regulation for a variety of products, from cigars to musical instruments. Anything requiring specific humidity protection benefits from Boveda’s solutions. Designed as sustainable and intelligent tools, Boveda packs are a simple yet effective way to maintain precise humidity levels, safeguarding items from the adverse effects of excess moisture or dryness.

Smart solution

The Boveda 49%-HA Size 40 4-Pack is a smart, reliable solution for protecting smaller wooden instruments. Designed around a completely sustainable approach, each 40g pack contains only water and food-grade salt in a precise ratio – no harsh chemicals, no gimmicks. This ensures long-term humidity stability, helping keep instruments in optimum condition while reducing the risk of costly repairs. Please note, this HA (High Absorbency) set is designed for countries and environments where the humidity levels are consistently over 60%: The standard version (RH, Regular Humidity) is recommended for lower humidity. It's important not to use Boveda packs alongside other humidity control products, as this can disrupt the self-regulating process. Simple, effective, and affordable, Boveda offers a dependable way to safeguard instruments from humidity-related damage.
