Roll On Tattoo Ink Ketchum 2oz.
Available in Green or black

Ketchum's Roll-On Tattoo Ink gives you the means to permanently and positively identify your animals.
Tattoos are a back-up solution in the event that a livestock tag is lost.
It can be extremely difficult to identify your animals that are the same breed. Tattooing your animals helps prevent confusion between the livestock.
Animal husbandry best practices recommend redundant identification methods for this very reason - and a good way to go about that is to use both tattooing and livestock tagging.
Permanent roll-on ink. Works great with any tattooer.
