Review on 📐 Sharpness Measuring Contour Duplicator by Jojo Howell

The product seems to do what it promises; It doesn't slide easily, however, and if you press hard on it, the contour will be distorted. I also don't like the beveled ends of the plastic parts. This makes it difficult to sketch the duplicate for cutting. To be honest, this is the first one I've tried, so I don't know if they all work the same way. I just wish this one would slide more easily.
