Original packaging should be retained \u2014 the clamshell and header card are part of the specimen\u2019s documented provenance. Store the unopened clamshell upright to prevent plastic deformation. If hooks have been removed from the packaging, store them in a sealed plastic container with a silica-gel desiccant packet to prevent oxidation. Avoid contact with other metals (copper, brass) which may create galvanic corrosion. Periodically inspect for signs of rust bloom or white oxidation; light surface oxidation is normal and cosmetic, but deep pitting indicates inadequate storage environment."},{"acf_fc_layout":"handwriting_analysis","title":"Handwritten Label Analysis","content":"The interior label bears handwritten annotation in blue ballpoint pen: \u2018Terry Tickle 3\/12\/2012\u2019.
