Dark Matter Putty contains tungsten and is a very heavy, non-toxic paste, ideal for adding weight to rigs. It is incredibly malleable even when fresh: it can be easily applied and shaped around micro swivels or knots, similar to balancing rigs with pop-ups. It can also be added to one of our Sinkers to increase its weight or to the end of our fused leaders or tubing to ensure they sink completely. You can be sure it will stay in place during casting and is available in weed green or gravel brown colors to match the bottom and other rig components. Each tin contains 25 g of Dark Matter Putty.
