Cheap plastic scraper blade!!!

Not a sales pitch...I just happened to come across this while searching for metal refills.

Maybe I'm just late to the party, but this seems way cheaper then some of the "tank specific" brands.

I use these to scrape my 3d printer bed attached to a window scrapper.

I actually ended up buying these to try

Does not work on coralline and aged algae unless you put some elbow grease. Works best on film algae. At least for me. Went back to metal blades for now.

I'm also going to order those, I like the handles better than what I have.
