This is a tool for removing sticker adhesive. The tip gets hot. Regular spatulas or newspapers have their limits when it comes to removing adhesive. I also replaced stickers myself. I did it well. However, it was extremely time-consuming and required a lot of space. I decided to sell it because I thought about just hiring a professional. You can save money by doing it yourself. If you want to try it yourself, please purchase it. Since it's made in a foreign country, I'm not sure if it's okay for 100 volts, but it seemed to work fine when I used it. The shop staff said it's at your own risk. Please use it at your own risk.
