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.
