The tips are numbered with 504pcs inside the box. These tips can be kept as Stiletto or can be filed slightly into the sides to taper them, or you can cut off the numbers, file into the sides, to make a tapered coffin shape. The tips have straight sidewalls, but a slight curve on top where they join to the natural nail to aid apex placement. Apply using base glue, then cut to the desired length, apply a thin clear acrylic base. Then go straight in with your chosen colour powders, and perfect the shape once capped in clear powder.
