This is convenient for marking fabrics you don't want to color, creating creases in fabrics that can't be ironed, and for seam allowance pressing. This is a cow bone spatula that fits comfortably in your hand and glides smoothly, being gentle on fabric. Cow bone, which is now rare, is more durable than other materials. Brand new, unopened. I have stored it without using it. Please consider purchasing after understanding this.
