Purchased 18mm Chinese blockboard for kitchen cabinet construction. Delivery was superb, 2days after ordering. Communication was also great. The delivery guy called to confirm he was on route and gave me an ETA. The product would have got 5 stars had the surface veneer been a little thicker. It really is as thin as paper and great care must be taken when sanding. But to be honest it's not a problem for my use as it's going to be spray painted. All in all very happy with product and service from sheet materials wholesale. I can certainly recommend this company and will be using them again.
