This Redwood slab is kiln dried and ready to use. It has a great workability quality as well as fantastic coloring! Most pieces have a beautiful striping figure present. Overall this all very lightweight material that we know you will enjoy! This slab would make a great coffee table or countertop! This slab has some bark incursions on the back face. There is a 2" split at the end opposite the numbers and 5" check along the numbered face near that split. There is a machine mark on one of the live edges that continues onto the numbered face.
