Do I have to use a fabric holder with Boveda in an instrument case?

YES! Always insert Boveda into a Boveda Fabric Holder before placing it in an instrument case. The fabric holder extends the life of Boveda plus acts as a liquid barrier if a pack is accidentally punctured.

Do I tear open the brown Boveda packet?

NO!!! DO NOT OPEN the brown packet itself. If your Boveda arrived individually wrapped in cellophane, remove that plastic overwrap before slipping the humidity control pack into a fabric holder.

Should I use a sponge or snake with Boveda?

No, do not use Boveda in the same instrument case with other humidification products, as this will reduce the Boveda’s efficiency. Ditch the sponges and hoses. No more rewetting— Boveda works automatically to balance the humidity in your case!

I live in a really humid place, so do I need Boveda in my instrument case?

Yes! Boveda makes a High-Absorbency pack to protect wood instruments in extreme humidity, prevent warping and curb humidity fluctuations when you’re in a dry environment, like an airplane or air-conditioned venue.

What’s the difference between the Large and Small Starter Kits?

The Large Starter Kit is the right Boveda for an acoustic guitar, large woodwind or large bowed or fretted instrument. Choose a Small Starter Kit to use Boveda with an electric guitar or bass, small woodwind or small bowed or fretted instrument.

最高だ．

きっちり湿度をコントロールしたければBoverda一択だ．一見高い商品だが，予想よりもちがよい．また，湿度を保つケースに入れるより小回りが聞き，コスパはそれよりは良い．アマゾンで在庫切れになることがあり，その点は残念だ．特に冬場は湿度管理をしたい楽器が多く，必需品となっている．他の湿度を保つと言っている商品とは雲泥の差で優れている商品だ．お勧め．
