Bottle Up - this toy measures 12" from top to bottom and is 2" in width. It is all stainless steel construction with some interesting items! The welded orings are 3.0mm thickness. This particular toy would be great for any medium sized bird such as Amazons or Greys and any similar size bird and also would be good for Macaws. It's a great toy to add to your stainless collection! It is also a favorite toy of my Blue & Gold Macaw!
