I have found the best way is to use regular hinged, velvet lined
jewelry boxes. Mine have my name stamped on the lid. I figure the
cost of each box into the price of the piece. You can get them from
Rio Grande but there are much cheaper sources out there. I buy mine
from a company here in Chicago and they have no minimums.
Makes great presentation/display and adds to the "perceived value"
of each piece. If a store or a customer does not want them, then I
recycle. They are a bit heavier/bulkier to carry but I find this the
befit out weighs the effort.
