High-Quality Material The plastic scraper blade is made of high-quality plastic that provides strength and stiffness, lightweight and anti-rust properties, sharp yet flexible. Comfortable Design Our plastic blade scraper adopts an ergonomic curved handle design, providing comfortable control and helping save time and energy. Multifunctional Scraper Tool This sticker scraper tool is ideal for removing decals, stickers, tints from windows, cars, walls, floors, and glass. Steel razor blades can easily scratch into auto paint, window tints, or other surfaces, but plastic razor blades can do the same job without scratching or shaving. Safe Scraper Tool Two slots on the back of the blade scraper securely hold the plastic razor blades to ensure the blade will not slip out. The plastic blade is sharp but safe and will not cut your fingers during use. How to Replace the Blade Turn the orange blade over onto the surface of a hard object. Press the blade at the same time and use your finger to eject the blade. Remove the old blade and replace it with a new one.
