4-Way Guitar Fret Polishing Blocks, 4-Pack, 240/600/1000/10000 Grit

Keep Your Instrument in Perfect Condition with Our 4-Pcs Guitar Fret Eraser Set. Maintaining smooth and shining frets is crucial for your guitar playing experience. Tarnish, rust, and dirt can cause string buzzing and reduce the lifespan of your strings. Our Flexible Sponge Sanding Blocks are designed to solve these problems effortlessly. Why Choose Our Fret Polishing Blocks? 1.Comprehensive Polishing:Each block is engineered with 4 different grits (240, 600, 1000, 10000). Start with 240 to remove heavy rust, use 600/1000 to refine the scratches, and finish with 10000 to achieve a stunning, mirror-like gloss. 2.Unmatched Flexibility:Unlike traditional rigid sanding files that might scratch your fretboard, our sponge core is soft and squeezable. It perfectly contours to the fret wire and easily reaches the edges near the nut and bridge. 3.Washable & Durable:The abrasive coating is firmly bonded to the high-density sponge. Just rinse it under water to remove metal particles, extending the lifespan of the blocks. 4.Perfect Size:Dimensions: 3.54" L x 1.38" W x 1.38" H. Weight: 0.25 oz per piece. Compact enough for your guitar case. 5.Package Includes:4 x Identical 4-Way Guitar Fret Eraser Blocks
