Bottle Shaped Silver Sleek Shiny Gloss 3 Piece Cocktail Shaker.
3 pieces are the lid, top neck with filter & main body, see images.
I understood this to be silver plated, but there are no makers marks or other marks to indicate this, so sold as untested white metal, and most likely silver or chrome plated.
Looks unused to me, only sign of wear is some slight oxidation inside the lid which may clean away.
Most likely a promo item, but no branding that I can see.
29x8.5cms approximately.
Nice item, ready to use & in good condition.
