Thorne Bros. Blade Tape is a unique 3M marine grade reflective tape. This is the same tape that is Coast Guard approved for use on Marker Bouys on some of the most treacherous bodies of water in North America. Amazingly bright when hit with any light this is a great ad-on to any existing bucktail you own! Thorne Bros. has this tape custom cut to fit perfectly on three different sizes of Colorado blades, but don't be scared to cut it to your own custom shape with a pair of scissors! Very easy to use, simply peal it off the backing and stick it on the blade-then go fishing!
