CUSTOM - Masterpiece Grimlock! - with 23.5 karat gold?!? Hey guys, I listed my customized Masterpiece Grimlock this evening. Please take a look and feel free to ask me any questions. Here's the link One thing that's cool about this custom...the gold is REAL! I gold leafed all the detail that you can see (not the chest) but the rings on the legs/arms, some stuff on his back and the claws. They came out ultra shiny.
