Review: A little small if you want this for nail art... - I bought this to achieve the velvet magnetic look with my magnetic lacquer (not gel) polishes. It has a much lower pull than the medium-sized magnet also produced by this company. However a couple of my fingers were too wide to slide easily between the poles of the magnet, and I couldn't paint my nails inside the magnetic field - so I bought the medium-sized magnet as well. However, as a magnet, this works perfectly well, so I didn't take away any stars.
Review: Small but mighty - Very strong small magnet, ideal for holding the shed rolling door open.
