As you can see, this one is nicely opaque.

I do put a paper bag inside it, to keep the rubbish from contacting the inner walls.
The depth of the etching and its sharp edges do not show up in my pics sadly, but it was the first thing I thought of when I saw the pic of the pink vase. The similarity of the very deep, but not well-finished and sharp edges of the etching. The surface of the black lines is smooth and shiney, but the "inner walls" of the etched away parts are rough to the touch, as is the white background.
The rim is polished.
