The high quality of the fat and seeds mixed in it ensures that your garden birds get the necessary calories and nutrients. The Giant fat ball is extra large (450 grams) and this fat ball with seeds can be offered in Vivara's specially designed basket. You can buy fat balls everywhere. Usually these are fat balls with a net around them that the birds can get entangled in and the quality of the fat leaves much to be desired. Vivara's fat balls do not have a neat appearance and are of very high quality. Weight approximately 450g. Please note: Feeder not included.
