I personally make, paint, & ship these Big Block Chevy Blocks. They are fabricated from black printed plastic & hand painted with silver. They take 24+ hours to print so please be patient if my shop is out of stock! I find that they make a great desk or workbench ornament. Feel free to message me with any questions!
