It's lucky this cute little piece came to me with the paper card shown, or I wouldn't have known was it was - I've never seen a 'tea snip' before! This makes a little tea, or a mug full of weak tea. The ball holds just a pinch, it's 1" across.
This is stainless steel, not marked that I could find (though I would have guessed it's English). It's nice and clean, plunger works well. The paper card is worn and wrinkled.
