This 5-piece contoured profile hand sanding block set is made from durable, medium-density polyurethane foam, providing precise control on delicate surfaces. The blocks are firm enough to flatten but have just the right amount of give to conform to small imperfections, ensuring a smooth, even finish. Unlike power sanders, these blocks won't leave swirl marks or scratches and can easily reach tight spots, all while reducing dust and noise. The hook-and-loop backing allows for quick attachment to any 5" sanding discs.

With two convex and concave radius blocks, this set is perfect for sanding inside and outside shapes in wood moldings, furniture, metalwork, auto body projects, and more. Suitable for both wet and dry sanding.

The base block can be used on its own for flat surfaces or attached to any of the other blocks for enhanced control and reach on curved surfaces.
