Product review (5 stars): Rico Multi-Instrument Reed Storage Case
I have had this case for several months and it did a great job with my Hempke, Vandoran and Rico reeds.  I haven't used the Humidity Control Packs yet, but I'm more than satisfied with the storage.  The flat surface has air grooves to allow the reed to dry and remain flat, and the strap going over the reed holds the reed in place with very slight pressure.  The case closes securely, and is easy to open and access the reeds.
