It looks like a regular patch, but if you flip it up, you can write your name. Clever patch that can hide your name from stranger. When using an iron, place the patch where you want it to be installed, and press firmly on a dry medium temperature (240 - 150 degrees Celsius) for about 20 - 30 seconds and then stick it on. When ironing, be sure to use a cloth with a damp cloth. Please iron the back of the product to ensure a sufficient adhesive. Do not move until it is completely cooled. When ironing, the color may transfer onto the surface of the cloth, so please use unnecessary cotton cloth on the mat.
