The main file, with its slim 8mm width, is perfect for smoothing mold lines on larger surfaces. Meanwhile, the round file features a pointed edge to reach into tight spots with ease. Both are made from nano glass, ensuring a scratch-free finish while also removing white stress marks to restore the plastic’s original grey color and flawless surface. Cleaning is simple—just rinse with water to remove plastic residue. For best results, pair these files with our Hard Plastic Clippers to expertly prep your models for painting.
