How do I protect a document/object containing possible fingerprints for examination?

If the case involves a document, please wear gloves when handling and keep handling to a minimum, place the document into a copy safe sleeve, then protect it between two sheets of cardboard inside an appropriately sized envelope.  If the case involves an object such as an aluminium can, bottle or piece of glass, please wear gloves when handling and keep handling to a minimum, place the object gently into a cardboard box (if sharp) or a sturdy envelope and minimise movement and frictional contact.

The more you preserve and protect your object, the less likely the latent fingerprint can be wiped or removed.

Please do not wrap objects with any materials such as bubble wrap or newspaper.
