After registering my brand through the county clerk's office I went to the area farm and ranch store to order a branding iron. A "box" with a letter inside. The guy at the farm and ranch store said that will not work as a brand, that it will always come out blotched because it is a "closed brand". Does any one have a closed brand? Box, circle, diamond, etc. Is there a way to make it work? Thanks for the input.
