(25 Pieces) PGN - 1/2 Inch (0.5) Precision Chrome Steel Bearing Balls G25

Perfect for science experiments!

They have a thin coat of grease on them when they arrive but if they didn’t they would probably rust so good for them for keeping it like that. Other than that I am just using them as weights and to kiddos some basic physics and they work great for that.

The bearings arrived quickly for a hobby project involving magnets and ball bearing. The bearings worked fine. DaVinci would have been proud.

I received what was advertised. I used it for a baseball pinball game I made for my grandkids.

Two thumbs up and five stars (easily).. These are very well made and look and work great... If I need more of these at this size I know where to get them now. Good day & God Bless... Randall M. Rueff K9RMR
