Instead of buying an entire new kit Recoil offer replacement bags of inserts containing a quantity of inserts (usually 10 but varies according to size) to replenish your kits. Replacement inserts are available to cover the whole range of kit sizes. Recoil also offer differing lengths of insert (kit standard is 1.5D or 1.5 x Diameter) ranging from 1D up to 3D for use in different material thicknesses. So when you buy a kit with 1.5D inserts you can buy a pack of 2D or 3D replacement inserts to go with it.
