This domed treat is molded from rice flour, vegetable glycerin, starch, water and a natural flavoring, with no plastics or polymers in the formula. It is designed to sit inside the cavity of Starmark Everlasting toys such as the Bento Ball, Treat Ball, Groovy Ball, Wheeler and Sprocket, turning play into a chewing challenge, though it can also be offered on its own as a snack. The domed version is formulated to dissolve gradually as a dog gnaws on it, so it tends to hold up longer than the ridged style of Everlasting Treat. Treats are produced at a dedicated facility in the United States. As with any chew, supervision is recommended, since small broken pieces can present a choking hazard and no chew product is fully indestructible.
