Marble double sink two meters in size, separated for 2000 two years ago

Marble double sink two meters in size, exactly like the picture here, I separated it for 2000 two years ago and now I changed it. The color is white, its flaw is that it got dirty and needs polishing by the representative to make it smooth. Don't miss it, I swear, the store owner told me not to let it go; it only needs polishing, but since I separated it, it's very expensive
