Congratulations on your new humidor! As with many cigar issues - personal preferences
always count first. Many of us who do own humidors (great & small) have a habit of
keeping the cedar boxes if room allows. Paper boxes absorb humidity and may result
in an unfavorable consistant reading on your hygrometer.

As for the cello, my experience is that when something comes individually wrapped for
my use, it usually performs better if I only unwrapped at time "enjoyment".
