This is a solid ebony slab with live edges. I believe it's rare to find ebony this large. I purchased it at a lumber market approximately 18 years ago. It has been stored indoors in a cool, dark place since then. I believe it is sufficiently dried. Thickness: 30mm Length: 1000mm, Width: 350mm There may be slight dimensional variations. As it is a natural product, there may be cracks or warping. Thank you for your understanding.
