Is the weather affecting your reeds? Consider keeping your reed case in a Humidor Bag (made for cigars), I prefer the medium sized bag, available at your local tobacconist shop or online. Just put a Rico Reed Vitalizer two-way humidity control pack (approx. $4-6ea.), I prefer the 58% humidity pack, in your Humidor Bag… and voila! Your reeds are now stored in a humidity consistent environment.
You may need to replace your humidor bag (approx. $7-10ea.) every 6 months or so, depending on the condition of the bag and zip-seal. If there are any tears or holes in your bag, or if it doesn’t seal correctly, replace it. The Humidor Bag cannot keep a consistent humidity level if not properly sealed.
When taking such good care of your reeds, you will notice that they last much longer than reeds susceptible to daily changes in temperature and humidity.
