Everything about these is super: super strong hold, super adhesive discs, super shiny and polished finish.
I became disabled with arthritis so I had to retire early, but I still have a very active mind. Thus, I have a lot of hobbies to occupy me. Most of my hobbies are aimed at keeping my fingers and hands nimble and providing a creative outlet. I make jewelry, I work extensively in metals and wire, and I do a number of needlecrafts such as cross stitch and restoring damaged vintage and antique linens and embroideries. I'm constantly dropping needles, pieces of wire, scraps of metal, etc. I have a magnet I use to help me locate dropped needles and other bits. I certainly don't want my cat to step on something or injest something harmful. The magnet I've been using is very strong. I got it at a fabric store for stowing pins and needles, or tacking patterns to metal clipboards. These magnets are at least 5 times stronger. I like that I can easily attach a long string or cord to one using one of the provided super sticky discs and just sweep it around my work area. They easily find my lost items even if they've become embedded in carpeting. I also sweep one across my body when I'm making clothing alterations to make sure I didn't forget or miss any pins. Yikes! The only problem I have with them is getting them apart. Just when i have one pried away -- victory! -- the others will snatch it back. Grrr. I love them. There are truly a million uses for them. Top notch.
