Ink for Chin-Ball Mating Harness Magenta

The stainless steel ball container of the chin-ball marking harness can be filled with ink of the desired colour. When a cow is properly in season she will receive very clearly identifiable back markings from the bull wearing the device. 

Each fill is enough to mark 25 - 30 cows (approx 0.5 litres). Marks fade in 4 - 14 days.  

We suggest changing colours on  a 3 week cycle to avoid confusion.  

Ink is available in 1 litre containers.
