Holder is shown with fuse for illustration purposes only - NO FUSE SUPPLIED

This is a genuine Blue Sea item, however there are a lot of fakes from the far east on eBay the easiest way to tell is on the side of the fuses and holders will be either BUSS or Eaton in text on the side as this is the manufacturer of the fuse holder for Blue Sea. If you visit the Blue Sea website you will see this clearly in all their pictures of the fuses and fuse holder.
