When it’s showtime (or class time), don’t risk playing with warped, cracked or moldy reeds. With the D’Addario Woodwinds (formerly Rico) Multi-Instrument Reed Storage Case, you can be confident that your clarinet or saxophone reeds are safely and securely held at an ideal 72% relative humidity. When placed in the storage case, reeds are held snugly to a grooved surface, which prevents warping. The airtight gasket ensures a proper seal, which keeps reeds safe and stable when traveling. The slim and sturdy case holds eight of any size clarinet or saxophone reeds, from E clarinet to baritone sax. Simply insert the included Reed Revitalizer Pack into the lid and you will have a clean and low maintenance way of keeping your reeds fresh with minimal wetting. The humidification pack helps extend the longevity of a reed and prevent warping and cracking by automatically adding or reducing the level of humidity within the case. Each pack will last approximately 45-60 days and then simply replace with a Reed Revitalizer Pack refill. For nearly a century, the name Rico has been synonymous with quality reeds. Now part of the D’Addario family of musical instruments and accessories, D’Addario Woodwinds has revamped the reed-making process to create the reed of choice among all levels of clarinetists and saxophonists, played in the world's most respected symphonies, conservatories, and jazz clubs.
