In the interests of honesty I need to say I havnt as yet been able to use these mats yet. The reason? They arrived so badly dented and creased That I cannot not use them in my machine as they are. I have a large wedding order that I had hoped to use the new technology on, the mats were intended to save tape and streamline the process. Now Iím not sure what to do. Until the shipping packaging is improved these mats are not worth buying online.
