Perdigon UV Resin Clear 10ml is our newest resin. We started to use it for tying our range of micro nymphs and perdigon nymphs using this reason. What we love at this resin is how thin it is and how fast and uniform is covering the entire body without trapping air bubbles. An extra advantage is in viscosity, due to the fact that the resin is ultra thin means that the layer remain thin and the fly will have a delicate silhouette.
