Small Horseshoe Alnico Magnets, 20-Pound Pull Red Cast Horseshoe Magnet with Keeper,U Shaped Magnet for Education

Ok this magnet is perfect for magnet nail polish! Perfect! Now what's fun...it comes in a crazy huge box, completely encased in Styrofoam. Which makes sense, strong magnet could mess up all sorts of things, electronics, medical devices. When it arrived, I had no idea what was in the giant cube packaging.

Got this for nails. Not nail nails but fingernails as in polish. Works fine if you have small hands

Worked perfectly for velvet effect nails using regular magnetic (Mooncat) polish.

I love the effect this creates with magnetic nail polish. It's just the right size, and the result has so much dimensionality.

Purchased for use with magnetic nail polish. It’s much more convenient than assembling multiple magnets and risking that they will disassemble mid-way into use and damage your manicure. There were a lot of warnings about not using this magnet by electronics and it was hard to remove the metal plate for first use, bit I got comfortable with this quickly and then it’s easy to work with!

Good strong magnet. Good for magnetic nail polish.

This was bought to use for nail polish. It is quite strong, so be careful with it! It is small and fits most of my fingers, but I absolutely can't fit my thumb in. I don't particularly mind, but if you intend to magnetize the polish on all of your fingers, you might want a different magnet.

Daughter wanted this magnetic for painting fingernails. The paint she uses has metal flakes which, when exposed to the magnetic field, align nicely and perfect coverage. It is sized just right for use with fingers.
