Review on FOSHIO Set Of 2 Orange Plastic Razor Blade Scrapers With 100 Plastic Blades - Ideal For Gasket, Sticker, And Adhesive Removal On Windows And Glass Surfaces by Mike Donathan

I always need razor blades. At Work, in the garage, etc. these plastic blade give me the same benefits as the metal versions but with less chances of scratching. Recent uses:Removed paint drops from hardwood floor; didn’t gouge finishRemoved old sticker from window; didn’t scratch glass (which a metal one can, make sure to use liquid when scraping glass)Gasket removal on a engine case; removed the gasket but didn’t damage the surface.BONUS: Surprised how well the plastic keeps a sharp edges. Figured if they did work, the plastic would be worthless after a few tasks. Not so; still got the original going with no issues. Got plenty of backups once it gives out.
