This toy is EXCELLENT for birds that love to shred paper. It's also great for recycling those old magazines! Just roll up a magazine and place it through the heavy, zinc-free welded ring and watch your birds play! This toy is also RE-FILLABLE, meaning if your bird chews the wood part of the toy, you may simply undo the c-clamp and put some more of your birds' favorite toy parts on it. Magazine not included.
