 The artifact is a cylindrical tin box of Kaliderma (brand) powder from the Pontifical Pharmacy.  The lid has the coat of arms of Pope Saint Pius X.

Kaliderma powder was a healing and antiseptic product prepared by a pharmacist by the name of Professor Alfonso D’emilio at the Pontifical pharmacy located at Via Imbriani, Napoli 5, in Milan.

What makes the item of interest is the coat of arms of the Pope on the lid.
