Frankly, there are better products on the market these days for storing reeds. I've found the Pro-Tec and Selmer reed cases (to name just 2) to be much better than the LaVoz Reed Guard for keeping reeds flat, protecting the tip, and not having problems with mold. Back in the day when I used LaVoz reed guards I often pulled out a reed and found it warped. Also problems with mold! I haven't had a single warped or moldy reed since I starting using a reed case. Normally, simply rinsing off a reed in running water after a gig or practice, drying it, and then putting it in a reed case works perfectly fine.
