One day my partner found a large piece of Black Walnut with grain patterns of a fish and we knew it had to be a Sushi serving table. Yes, this is a piece of solid Black Walnut - hand cut and the edges carved to a smooth finish. All other grain patterns and knots were completely natural to the piece of wood and we altered nothing. You can see shades of white, blues, and grays, surrounded by brown and black in this unique piece. We finished it with 10 coats of food safe Salad Bowl finish to add to its durability. Not into Sushi, this serving table makes an excellent place to show off your fav hors d'oeuvres. Great as a centerpiece for your table when not in use. Dovetail joinery so no metal, pins or dowels were used. Measures: 23 x 6 (widest part) x 2 (inches) Hand wash in warm soapy water after each use.
