Knobby Starfish 1 1/2 to 2 1/2". Imagine holding a piece of the ocean's ancient story—a knobby starfish, weathered by tides and time. Each specimen carries its own character, with textured bumps and ridges that tell of life on the seafloor. These natural starfish, ranging from 1½ to 2½ inches, are perfect for collectors, coastal décor, or anyone drawn to the quiet beauty of the sea. Sustainably sourced and individually unique, every starfish is a small window into the underwater world. Sold individually, so you can choose exactly the one that speaks to you.
