Dark Matter Putty contains tungsten and is very heavy in relation to its size, making it the ideal rig putty that you can use for everything when it comes to weighting your rig. The putty is non-toxic and highly malleable, even straight from the tin it comes in. This makes it easy to apply around micro swivels or a knot, such as when you want to balance a pop-up rig. It can also be applied to one of our Sinkers to give it some extra weight, or to the end of fused leaders or tubing, to ensure it sits firmly on the bottom. It stays in place well during casting and is available in Weed Green and Gravel Brown, so you can decide which colour best suits the bottom you are fishing on and your other rig components. Each tin contains 25g of Dark Matter Putty.
