How do you put nameplates on halters? Can they come off once on?

Maybe just get one custom made and ask them if it could be removeable? They often make the halters with one on and just ingrave the name onto the panel but if you ask for it to be removable they may be able to help
Greenhawk (horse store) puts them on and they are hard to get off but they can
