(10 Pieces) PGN - 3/4 Inch (0.75) Precision Chrome Steel Bearing Balls G25

Will buy again.

I use them in physics classes as they are replicas of experiment by Galileo, Newton and others for classic mechanics.

As described. Delivered promptly.

Used to replace old penball machine balls.

Just as advertised.

Crafting was easy.

These are round, weighty, and steel.

Ordered these for crafts with paracord. Love them! Perfect, lovely, shiny spheres!

I now have balls of steel and its awesome. Nice clean balls with no flaws on em. I got these to replace a trackball that was worn out, and they fit fine but stupid me discovered shiny steel balls make terrible trackballs. So now I just have a bag of stainless steel balls in my junk drawer. But I can now say with pride and confidence, that I do indeed have balls of steel. And I can prove it.

Tenía un proyecto universitario de un levitador electromagnético, necesitaba una esfera metálica de un tamaño y peso especifico para los cálculos obtenidos en la hipótesis. Definitivamente es de buena calidad y no se rompen al caerse o usarlas.
