After years of trying pretty much every known ear tag on the market, I decided last year to go with brisket tags on the retained animals. I settled on BOC-LOC tags that you write on, and used my Allflex pen to write on the tags. Unfortunately, the ink formulation simply doesn't stick on the tags. So I tried my No-Z pen, and had the same problem. I've taken to engraving the numbers now, but its difficult to read from any more than a couple feet away.
So, anyone used these brisket tags and found something that will write (and stay) on them?
