◎ This is a heat pen that uses AA batteries. ◎ Operation has been checked, so you can buy with confidence. It heats up in a few seconds after turning on the switch, making it very easy to use. It finishes more cleanly than burning the thread with a lighter. You can process it at the edges, so you can leave the thread shorter than with a lighter (Image 3). If you cut the thread directly without using scissors, the finish will be worse. This is a product that I also use, so please feel free to ask if you have any questions. I use rechargeable batteries. In addition to leathercraft, it can be used for various other purposes such as processing 3D printed products, plastic models, wood burning, and lost wax casting for metalworking. ・The material of the cap has been changed from the conventional product.
