ALLFLEX White Marker Tag Ink Pen
One tag ink pen with two marking tips (fine and broad).
Easy to hold and easy-to-use pump action. Fade resistant black ink.
Best results are obtained by shaking the pen thoroughly, writing the ID once on the tag using the Allflex tag pen, letting the ink dry and then writing over the ID a second time. Following these steps should provide you with an ID that is readable in the paddock for years!
