4.7mm Neodymium NIB Magnet Spheres with Steel Case - Gold (216-Piece Pack)

Pros: Its a very interesting toy that takes all your day, if you let. You can make alot of things with these little balls. My friends came to my house just to play with it. Comes with a little case, and its rare.

Cons: The color get out in a few days and turns to silver with no shine. The old color stays in your hands till you wash the same. Its a harder than looks, to make the 6x6x6 I take like 2 days, than it became easy. Feels like it losts the force with the time. Its VERY easy to lost some ball and with that you couldn't make the 6x6x6.

Other: Too many expensive, you can buy it for much less.

Pros: - the metal case beats almost all the brand name similar magnet toys. it provides good shielding so your magnets won't affect anything else
- the balls have good uniformity. Unless you measure them with a caliper they're all identical to the naked eye
- the gold shine is ok. It's not gaudy or overly shiny. Someone even used my magnets as jewelry a couple of times.
- Magnet strength is good and on par with brand name magnet balls.

Cons: - they were a bit lubricated on arrival with some grease. It washed off.
- I did manage to scratch one of the balls. It scratched through normal use so I don't know what to think.
- the case was PINK!
- playing with them is addictive

Other: It was cheaper than brand name and it came in a metal case that's better than the other magnet ball cases.
