Review on Rannb Stainless Corner Brackets Mending - Secure your Corners with Durability by Sean Burnett

What I was looking for. Yes they are flimsy but as advertised and I wanted them to be able to be bent so it works well. Some have complained that they look like painted scrap metal, but the white material is protective tape. Remove to reveal the polished side. I can't verify the chemistry or percentage of Cr, but it's non-magnetic and quite hard (hacksaw is blunt).
