Fret Collars - Dunlop, System 65, for fret polish without taping
The Dunlop System 65 Fret Collars include everything you need for a quick fret polish without the need for taping the entire neck. Two sizes of flexible steel collars are included, 0.125 and .080. The 8000 grit polishing cloth will remove corrosion to reveal the shiny surface of the frets for a nice finish as well as smooth string bending.
