Shaped to fit comfortably in your hand. Use for pressing seams you would normally finger press. Perfect for foundation piecing, patchwork and appliqué. 

I do alot of foundation triangles ala Triangulations 2.0 and paper piecing. Strong finger nails are so helpful, but I find that many of my students do not have such good fortune.  The finger presser is a terrific alternative.  It allows you to finger press to your heart's content without a single thought of your manicure.
