Gatku Pole Spear Bands (?)

New/Old stock... these came with a large collection of sphere fishing equipment including a number of Gatku pole spheres.  Honeslty I'm not 100% certain exactly what these are for, but I surmise they are replacement bands for the longer poles or for rigging breakaway lines/etc.   Either way... here is a deal on brand new bands as pictured.   See photo for lengths written on the blue tape.  The length is the distance of the rubber, not including the line.
