High Gloss |
The gloss of the created surface finish is highly reflective after the polish of the male mold before making the mold. This high-gloss finish provides high transparency and is beneficial for cosmetic pieces, lenses, and other surfaces that can be easily cleaned. |

Semi Gloss |
This B level finish doesn't reflect light strongly yet provides a bit of luster. By utilizing rough sandpaper, smooth, washable surfaces can be achieved, falling between high-shine and dull. |
