Use this Vintaj reliefing block to highlight raised relief designs on your metal jewelry components. The specialty color-coded grits allow for sanding, buffing, and polishing metal. The heaviest grit (dark gray sides) removes paint and patina from raised areas. The medium grit (white side) lightly highlights and reliefs embossed and raised areas. The finest grit (light gray side) buffs and polishes. It fits in the palm of our hand and was created especially for sanding the raised areas of Vintaj metal products, to show off their fine detail. You can also use this block on paper goods, polymer clay, chip board, grunge board, wood, leather, acrylic, textiles, foil, canvas, and more.
