Marbled bricks are created when changing colors -- the old color from the last production run is flushed out of the mold, and the new color comes in, creating the marbled look.
These were never included in any sets, and Lego generally destroys these bricks.
These are similar to the famous Grangemouth bricks, and may be of interest to people who collect misprints, error bricks, Q-parts, and other unique Lego parts.
Given how rare this is -- it's essentially a one of a kind item -- it's quite difficult to price them, so please feel free to make a reasonable offer, worst I can say is no.
I will combine shipping, in general you'll pay shipping for only one item and everything else will ship
free, so add this to your cart and
