Screws don’t fit
Color: Beige
Looks beautiful but came with a deficient screw. Screw doesn’t fit and thus can not complete building.

Great for organizing
Color: Black3pro
Arrived as scheduled. Just as pictured. I'm happy with my order. They Do Require full contact to support weight. Panels with bends cut down on what they hold ( slide down under load) I put a piece of tape below the magnet & it stopped the slide. They work great for my smaller shovels & tools.

Perfect. Strong Magnets. Good Plastic Sleeving. I have bought Twice.
Color: Black3pro
Very Handy! I ran out of room for my cordless tools and had an entire side of my toolbox. I bought these and hung the tools on them. Problem solved. No fasteners, no extra wall space. They hold even my heavier cordless tools.
