Fulling Mill Tungsten Jig Backs- The Fulling Mill Tungsten Jig Back weights are designed to resemble nymph bodies and will help your flies sink quicker whilst keeping the body as compact as possible. These jig back bodies are made from high quality tungsten and can be easily tied onto your hook thanks to the slot on the underside of the body. The heavy tungsten weight will make your flies sink fast and the small shape allows you to keep your flies small in size yet dense in weight that will sink very quickly into the feeding zone. Perfect for nymph patterns. High quality tungsten for added weight. Supplied with 10 per pack.
