Product review (2 stars): Get the Boveda 10 pack for $9 and save your money
As far as the product goes, it works fine.  But when I reordered this to replace the dried out Rico Reed Vitalizer Humidity Control Single Refill Pack that was in my son's Rico reed case, guess what I got?  A single packet of Boveda humidity packet - it was not even re-labeled as Rico, but came in the same Boveda brown packet.  I always wondered if there was something unique about the Rico packet, and apparently that is not the case.  I got 10 Boveda refills for $9 instead, which seemed to be a much more reasonable price to me.
