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

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.

Perfect weight for Fidget Spinners

Good product

Theyre pretty cool using them for a marble track. Standard marble is not a half inch by the way so I just scaled my marble track down but they are a great product perfect for my application.
