Package tracking showed my magnets came in, but were delivered to the wrong address! They went to my old apartment, which luckily was near my workplace. I picked the box up at lunch, and in 2 vials were the two types of magnets I ordered.
In the time following my order to United Nuclear, I found out that most companies simply will not coat magnetized magnets provided by a third party. As such, the magnets that came in are now just for fun. I got 6 x .25" spheres and 50 of the discs I was planning to get coated for implant. With the larger magnet I can make the small disc move and rotate from a considerable distance. Very promising!
