4 Pcs 6" Solid Steel Floating Shelf Bracket Blind Shelf Supports- Hidden Brackets for Floating Wood Shelves Concealed Blind Shelf Support – Screws and Wall Plugs Included – Black

They are sturdy but absolutely crooked the tilt downward- didn’t realIze this was a common issue with this product so I didn’t check beforehand but the end result is pretty wretched and a huge waste of time. Now I’ll have to remove a bunch of anchors and order a new product.

Very nice, easy to install.
