The Little Heart 4 oz seed block makes a great gift and fits inside any suet cage. Or hang it on its own from the red raffia hanger that is included. This petite feeder is made from solid seeds: black oil sunflower, pecans, peanuts, and millet. It is not affected by hot or cold weather and will not melt. And because there are no shells, there is no mess beneath. Each heart comes individually wrapped. The small size makes it an excellent stocking stuffer. 8 x 9cm (3 x 3.5").
