(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.

Very nice .50 steel balls. Seem to be ideal sling shot ammo and ball bearings. I think theese resist rust more than some steel ammo.

We use them in our after school program to test the viability of our engineering projects.

received quickly. good quality.

Just what I needed, everything was in great shape. No rust or deformities.

Good

seems excellent so far

Product arrived the next day. Very happy with the mixed collection of PNG bearings. Just the correct size for the projects of making monkey fist keychains, monkey fist zipper pulls, monkey fist impact tool.

Size is perfect for smaller monkey fists...will order again when needed.

Exactly what I ordered. But I I am a dumb dum and ordered the wrong size. Lol
