Inter-Sleeves are the inner weighted section of the Inter-Lure and are made from an environmentally friendly tungsten compound. They come in a variety of colours and patterns including a small range of realistic lifelike printed patterns. Available in 47.5mm/10.5g, the Inter-Sleeve is interchangeable with the entire range of 40mm 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.
