Separate each bone from the stem. Place the stem in a separate bag. Date this, and include sufficient verbiage to describe contents.
Using the tips of your fingers, gently sort your bones into careful piles. Separate, bag, date, and properly identify each piece.
Use your sculpting prowess to create a shipping container of precise diameter to accommodate the bones and stem with no opportunity for shifting.
Gently, thoughtfully, place each bone with grave and terrible care in the package you create in step 3.
Affix appropriate postage and labeling.
