Eltham Walnut 1.68m2 Flooring PackEltham Walnut is a designer's dream. The deep tones of Walnut make this floor a unique and eccentric choice. Select grade is likely to contain some boards that have a higher number of knots than Prime, and you should also expect some of these knots to be larger in size. There is a possibility of some sapwood and small cracks and filler are likely to be present. A greater level of colour variation in the timber is to be expected. Specification Product
