This embossing device is designed for creating hollow lace edges on DIY greeting cards. It is a labor-saving tool that can be used to press borders on cardboard. The device is available in two sizes, small and extra large, and can press cardboard weighing around 80-200g. Please note that it is not suitable for pressing sponge paper, hard cardboard, non-woven fabrics, or other tough and thick materials, as this may damage the embosser. The pressed pattern may have a little burr due to the fibers in the paper, but this can be removed by touching it with your fingers.
