My love birds absolute favourite toys. I've bought three of these in the last year each time replacing them after being completely destroyed. Inside is stuffed full of shredded paper the toy itself is bound with some bird friendly twine and the outside is a hard shell like palm leaf. My love birds can adequately destroy the large and love to perch on it and in it. Treats and food can be hidden inside it to encourage foraging but my birds just love destroying it. You can reuse the shredded paper as well for foraging toys if your birds destroy the outter shell.
