  • Chrome coating doesn't hold up, corrosion sets in quickly
Number of Items: 25
I bought these to use with my children's "Gravitrax" toy, since they're constantly losing the marbles under furniture or misplacing them. While these may work fine for their "intended" use in a mechanism coated with grease, I would think that a chrome coating would protect the steel from corrosion from the oils on your skin. Not so, while the "official" marbles are still smooth and shiny, these ball bearings dull and rust quickly after a few uses. The upside is, they're cheap, they're the right size, and they roll just fine on the track. I can't speak to their function as ball bearings, but as marbles, don't expect them to hold up if they're handled much. ... show more
