Knots galore for the bird who loves to unknot, untie and do lots of tongue exploration! The center of this toy is a natural wooden bead with an all natural, chunky block of wood on each side. Two wood blocks with a center bead separating them make this toy approx. 8-1/2" in length and 1-3/4" wide. Colorful sisal ropes are strung through the sides of the blocks and are knotted on each side making it fun for your bird to play with. This is such a nice chewing toy for the medium to large birds. Hangs with a bird safe quick link.
