Although these devices have been "implanted" in ESD sheeting, they were not in sealed packets and the result is that you can see small "dots" of oxidisation on the metal case both topside and around the side.
Gold plated legs are fine though
Stored on ESD foam (to protect the legs, these are not static sensitive) and now in SEALED clear plastic packets to preserve the condition.
