These 2 cups are a food safe biodegradable plant based product. Each one has a piece of dried fruit and a couple of pieces of nuts like walnut, almond, pistachio or cashew. It is assembled with hemp rope, paper decorations, two wooden beads on the outside and one on the inside. Fun for your birds to learn foraging. I can customize them with which nuts or dried fruits your parrot would like if you email me a preferance.
