This is exactly what your cleaning kit is missing! That little compartment on the top of the kit would hold these strings. They did not use patches to clean the bore of the k98; they used strings like this. The price is for 2 small bundles (each containing about 15 strings give or take). This is roughly enough to fill up our cleaning kit. A great item to complete your kit or even to use when you do rifle cleaning displays. These are newer made.
