This is the first factory test from Santa Cruz Skateboards. These are sent from the factory to ensure quality and art work printing. This poster version passed neither as the top layer was not supposed to have fiberglass and the coloring was off, causing Leo to be dark purple and Don being pink.
The No 18 was written by R&D to keep track of decks that go in the strength testing process but this colorway was saved from that because of their defect.
