Tianli Black/White Buff Polishing Disc：

Serves as the final step in the stone polishing process. It is specifically designed to eliminate ultra-fine scratches left by the previous 3000# stage, pushing the stone surface to its maximum brightness.

Not a difference in gloss level, but a color-matching principle. White Buff pads are used for light-colored stone (e.g., beige marble); Black Buff pads are for dark-colored stone (e.g., black granite) to prevent resin pigment from penetrating the stone and causing color differences.

The three-slot continuous rim design effectively removes debris and dissipates heat, maintaining uniform contact pressure during grinding to produce a strong mirror finish.
