SHIPPING FRAGILE DISC RECORDINGS SUCH AS SHELLAC OR GLASS

It is suggested that you double box them.  Here is an example for twelve 10 inch 78 rpm recordings. First, make two stacks of 6 and put a sheet of corrugated card board on each side of each stack.  Tape each stack on four sides.

Then take the two stacks and tape them together and put them in a box close to the size of the combined stacks. Use appropriate soft padding between the combined stack an the walls of the box. Foam, popcorn pellets or bobble back is good.

Take that sealed box and put it into a larger box (2" or more on all sides), with padding as described or small balls of crumpled single sheets of newpaper.
