This fine small silver box is for holding the opium block. Such blocks were small (but of high value). They also tended to ooze in warn conditions, so a heavy-gauge box was needed to store them, preferably with a heavy, or tight-fitting lid. Opium also needed to be kept in air-tight conditions, so again, a good lid was needed.
The lid is surmounted by a fine, crouching solid-cast silver mythical creature.
The sides are decorated in chased, high relief, with Daoist symbols. The side of the lid is etched with a key-fret pattern.
The base is stamped in Chinese with the word for ‘perfect’.
