This is the right size Boveda for:

• A tight-fitting instrument case for an oboe, clarinet, flute or small woodwind
• A case or tube for a bow used with a violin, viola, cello, bass or other stringed instrument

Using Boveda:

• Requires zero maintenance—no more filling messy hoses and snakes and wetting sponges
• Maintains an ideal relative humidity range for bows and woodwinds—45-55% RH
• Prevents humidity fluctuates to limit bow hair movement
• Reduces expansion and contraction of wooden instruments
