I use EZid tags from EZid, I use the medium size ones with the daisy stud. With these if the tag gets hooked on something it will pull the stud thru the stud hole and not rip out the ear. if the stud gets caught it just folds over and releases. I have used them for 2 years now and are very happy with them. Contact them at 877-330-3943 Elsie will be the person you will be talking too, and she is good. She probably will be at the NADEFA conference that is where I seen them
