This is a 16-piece contoured profile hook-and-loop hand sanding block set, made from durable, medium-density polyurethane foam. The blocks are firm enough to effectively smooth surfaces while offering just the right amount of give to conform to minor imperfections, ensuring consistent sanding. They provide excellent control for sanding delicate surfaces or edges, allowing for precise and gentle material removal.

The blocks are 1-1/2” wide and 4” long, making them ideal for sanding intricate convex and concave shapes. The hook-and-loop backing enables quick attachment to any compatible sanding sheets, or you can cut sanding discs to fit.

This set includes a variety of contoured, convex, and concave block shapes, providing nearly every profile needed for sanding complex wood moldings, furniture, metalwork, auto body work, drywall, fiberglass, plastics, craft projects, or any uniquely shaped surface. These blocks are suitable for both wet and dry use.

The included base handle attaches securely to any of the blocks, offering improved control and reach. The teardrop-shaped pad helps press sandpaper onto both concave and convex curves.
