Crafted in small batches from semi-rigid and durable urethane, they are solvent-resistant and are easily sanded for minor adjustments. These fins can also be heated and shaped for custom presentations. Fits 15-17 inch, Brown Trout. Tail overall width: 120 mm. Caudal Peduncle width: 43 mm. Tail Overall length: 72 mm.
