This is a 3-pack of nice large 80mm (3.2") chrome wire sound hole covers. These can be screwed to either the outside or inside of the box, above or beneath (or both!) your sound hole(s), to give your CBG a very distinctive look. They also make great cigar box amp speaker covers, and are actually the same ones we include with our Cigar Box Amp kits! Mounting screws are not included with this offer.
