Inter-Sleeves are the inner weighted section of the Inter-Lure and are made from an environmentally friendly tungsten compound. The life like printed range currenly consists of 5 realistic life like prints including Baby Bass, Rainbow Trout, Brown Trout, Red Fin and Pike. They are 47.5mm long, 10.5g and suited for the 40mm range of Inter-Shells. The Inter-Sleeve is interchangeable with the entire range of equivalent sized Inter-Shells and so purchasing a colour or pattern is actually an investment into the system. Inter-Sleeves are easily added removed or swapped without the need for cutting the line.
