This is one of the coolest shredable type toys we have. There are four large 5" willow rings, and five large 5" birdie bagels. The neat part about this toy is, your bird has to chew most of the rings completely before they fall off. The reason is, the center, which you cannot see, is a very long, large birdie bagel. Plus, when all the willow rings, and birdie bagels are gone, you will be left with some neat beads and more for a surprise center. Any bird will enjoy this toy! You can also put treats inside and use it as a foraging toy. It is hung with 2mm stainless steel chain and o-rings and hangs by a stainless steel 3.5mm mm wide jaw quick link.
