We are sorry to hear that your 12" Gear Tie broke. The more you can mitigate tying the GT off in the same spot, that will help preserve the wire inside. If you can wrap the tie around your application versus tying it off, will also go a long way to keeping the tie from severing. That said, please contact customer service at info@niteize.com or at 800.678.6483 8-5 M-F MST, we would be happy to replace the broken 12".
