The 25mm fuzzy balls are big fuzzy baits made of TPE (Thermoplastic Elastomer) that is highly stretchy, durable, and buoyant soft plastic. This stuff is incredibly tough. Made to the same specs and from the same factory as the Hag’s Prickly Pear, and the Arsenal Morning Star Urchin. They are bigger than the 19mm Hag’s Prickly Pear, but identical in material and design.
