A VERSATILE TOOL: This scraper is ideal for removing vinyl, dirt, stickers, signs, glue, labels, grease, and paint from glass, walls, appliances, metal, ovens, and much more. These plastic scrapers are particularly effective for removing labels, dripping wax, and even melted plastic from 3D printer build plates. You will find this small tool very handy. EXCELLENT PERFORMANCE: An excellent cleaning tool. The plastic blades do not penetrate the surface like a razor blade, are easy to use, and remove stickers without scratching. EASY TO USE: The notch in the handle of the plastic scraper is specially designed for your thumb during use, providing optimal control and comfort. In addition, changing blades is easy and safe; a flick of the wrist removes a used blade and a light push inserts a new one. PACKAGE INCLUDES: 4 scrapers and 100 extra double-sided plastic blades for daily use and replacement of worn blades.
