Flexible Curve Ruler 12 Inch Ruler Bendable Curve Template, Double Side Scale CM/INCH Rulers 3pcs for Engineering Drawing and Sewing Pattern Making

The Flexible Curve Ruler is designed to assist users in creating smooth, precise curves, which can be crucial for engineering drawings and sewing pattern making. Overall, customer feedback indicates a mixed reception of this product, with some users appreciating its affordability and versatility, while others express concerns regarding its functionality. Many customers, including educators, note the ruler's great quality and value for money, particularly praising how their students have embraced these flexible curves. The product's compact design is viewed positively by some, though a few users had expected a longer ruler for their needs. On the downside, several reviews pointed out significant issues with the product's performance. Specifically, the metal insert that provides rigidity to the ruler does not extend to the ends, causing them to protrude awkwardly and render full use of the curve difficult. Users looking for a ruler that maintains a specific curve while transferring it to another surface have found the lack of strong retention to be a hindrance, leading to frustration and leaving it less effective for various applications. In summary, the Flexible Curve Ruler serves well for basic tasks and offers an economical option for users, but its performance limitations may deter those seeking a more robust tool for precision work. **
