Hi Adam,
Unfortunately I'm neither an expert or collector of these things but I do have a very similar one, mine has tigers and Chinese characters on it and its lid is brown rather than black.
Approx: 10cm tall.
It came in a little silk and cardboard box. My niece purchased it in China last year.
I have assumed mine was probably made for the tourist market as a souvenir.
Cheers
Meegs
