I agree with David Lennick about syrofoam chips for shipping 78s. They are
a pain to the recipient, not only because as he said they fly all over the
place and adhere to almost everything because of static charge, but because
shards of them wind up inside sleeves and on the records. If one wants to save the
sleeves, both must then be rid of them in addition to any necessary cleaning
of the records. I also agree that they don't always protect against breakage.
Crumpled newspaper has always worked for me and my recipients.
