Product review (5 stars): My son loves this for his clarinet & sax reeds.
Got this for my son for 5th grade band.  He was killing reeds, in part because of learning, but I also remember the hurry getting ready before band started.  When ordering another large box of reeds Amazon recommended this, it has made a HUGE difference in how long his reeds last.  I haven't tried using a reed that was in so I don't know if it has made a huge difference with anything else, but for use it has significantly increased the life of his reeds and that makes it worth every penny.

It's way cheaper to buy the refills&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Boveda-72-Rh-2-Way-Humidity-Control-8-g-10-Pack/dp/B00JV27MJU/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Boveda 72% Rh 2-Way Humidity Control, 8 g, 10 Pack</a>&nbsp;the $13 pack will last use about 18 months, and that is way cheaper then having to be decent reeds more often.

I also love how big it is because he can keep both his clarinet & sax reeds in it and more then 1 size of each if he wants/needs.
