When I used to make lots of jewelry and was buying lots of lampwork, I quickly found that beads shipped without spacers were far more likely to break! I was a factor in what I purchased... But as a bead maker, I don't think of it... partially because I pack my beads so carefully and I make mostly focals. But for sets, anything with surface decoration goes into it's own 4ml ziptop baggie. Beads w/o surface dec are packed together but only a few. All zippies go into a jewelry box... freebies in zippies on the bottom, cotton, beads and a piece of bubble on top. Box is tied with ribbon and shipped into bubble mailer.
