YTEXMale Buttons Ear Tag BLACK All American Identification 25 Count

Good so far, they seem to match up in size with the backs that come in a pack of 3star sized ear tags. Will update after use

Very specific back for my particular ear tag. You get what you pay for ~

ya gotta have 'em they are great

These are just the ticket as we have lost a whole pack of the ones that came with the tags.
