23.5" Lake Salmon Wood fiber composite - whats this mean? Much less maintenance than your average serving board! This piece is made from super compact saw dust. Crazy huh? It's nonporous, and super resistant to knives. This is what you'll find on the reverse side of the salmon because the front is completely covered in resin. Not as scratch resistant but completely odor and water repellant. Perfect for your sushi platters Complete care guide included
