Review on Multi-Purpose Plastic Razor Blade Scraper Tool - 2 Pack With 100 PCS Blades For Easy Paint And Sticker Removal, No Scratch Cleaning Of Car Windows, Glass, Wood, Floors, And More! by Fritz Marrero

Its a hard plastic both the blades as well as the holder but with use the plastic wears down so adding and removing the blades could make the grip of where the blade goes weak. I don't like that the blades are plastic, i used about 30 of them to take off an old sticker on my car and it hasn't come off completely. The blades will get a chip or a (dent if you will) and will scratch or incorrectly remove something you want off. For the car sticker, i think im going to order a metal blade scraper with a real razor blade.
