This is an acrylic corner ruler that can be used for leathercraft, other handicrafts, DIY projects, and more. It's very useful to have one because it can create various types of curves. Also, the transparency makes it easy to see the object you're working on. Please use it to improve the accuracy of your work, such as making wallets and bags. If there is a protective film, please peel it off as shown in the second image. *The shape is different from the one in the second image.
