UNGERProfessional 4” Replacement Window and Glass Scraper Blades, 5 Pack, Includes Storage Case, Carbon Coated Tool, Remove Gum, Stickers, Paint, and Adhesives

Excellent blades! These are very high quality blades and the only ones I use for my small cleaning business because they are scratch proof and last a very long time so you will not have to worry about leaving scratches on any surface or replacing them constantly. They do not dull quickly. I have used these on tile, marble, granite, glass, even fiberglass showers to get soap scum off. You do not need to push hard- let the blade do the work. It will take less effort than any other blade. Just slide the blade across the surface.

They actually fit

Worth the money

Great blades. Seem to stay sharp longer than other brands. Buy online as Home Depot and Lowe’s always seem to be out of stock.

They do what they're meant to do with it's corresponding holder. They're sharp (duh) and well oiled so that they will last longer while stored in it's nice little box. Fair price for the amount of blades that it comes with. I feel that they dull out 6 or more months after use (I use these on my glasstop stove 1-2 a week) ... or if the rust get's to it first (since I rinse it off with water and sometimes I forget to properly dry it out).

The double edged blades are long lasting and easily scrape hard flat surfaces clean.

They are sharp but rust out very easy
