Thirty jumbo 3/4" thick & 4-7" long fat pine wood slices are knotted individually to natural sisal rope.  Most of the blocks are natural and undyed, but I did add few gumdrop polkadots for some color.  Big Cockatoos, Macaws and avid wood chewers will love this toy.  Designed on a stainless steel base and hangs from a big wide-jaw stainless steel quicklink lock.   15" long and 14" wide.
